[{"id":47208,"question":"Quel est le nom systématique du composé CH3-CH2-CH=CH2 ?","option_a":"Butane","option_b":"But-1-ène","option_c":"But-2-ène","option_d":"Propène","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le composé CH3-CH2-CH=CH2 est un alcène avec une double liaison en position 1, donc son nom est But-1-ène.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"Butane\", \"b\": \"But-1-ène\", \"c\": \"But-2-ène\", \"d\": \"Propène\"}}","_debug_options_count":4},{"id":47209,"question":"Les alcanes sont des hydrocarbures saturés.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Les alcanes sont des hydrocarbures saturés car ils ne contiennent que des liaisons simples entre les atomes de carbone.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\": \"Faux\", \"c\": \"\", \"d\": \"\"}}","_debug_options_count":4},{"id":47210,"question":"Quel est le produit principal de la réaction entre le propène et le dibrome (Br2) ?","option_a":"1,2-dibromopropane","option_b":"1,1-dibromopropane","option_c":"Propane","option_d":"Bromopropane","option_e":"","option_f":"","bonne_reponse":"a","explication":"La réaction d'addition du dibrome sur le propène donne principalement le 1,2-dibromopropane, car la double liaison est rompue pour former deux liaisons simples avec les atomes de brome.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"1,2-dibromopropane\",

CnH2n-2.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"La formule générale des alcynes est bien CnH2n-2, car ils contiennent une triple liaison qui réduit le nombre d'atomes d'hydrogène par rapport aux alcènes.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":

?","option_a":"But-2-ène","option_b":"Propène","option_c":"Pent-1-ène","option_d":"Éthène","option_e":"","option_f":"","bonne_reponse":"a","explication":"Le but-2-ène est un isomère de position du but-1-ène, car la double liaison est déplacée de la première à la deuxième position.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"But-2-ène\",

l'eau.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"La combustion complète d'un alcane, comme le méthane (CH4), produit bien du CO2 et de l'eau : CH4 + 2O2 → CO2 + 2H2O.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\":

?","option_a":"But-1-yne","option_b":"But-2-yne","option_c":"Pent-2-yne","option_d":"Hex-3-yne","option_e":"","option_f":"","bonne_reponse":"b","explication":"Le composé CH3-C≡C-CH3 est un alcyne avec une triple liaison en position 2, donc son nom est But-2-yne.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"b\", \"options\": {\"a\": \"But-1-yne\",

polymérisation.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"a","explication":"Les alcènes, comme l'éthène, peuvent polymériser pour former des polymères comme le polyéthylène, ce qui est une propriété industrielle majeure.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Vrai\", \"b\":

?","option_a":"Chloroéthane","option_b":"Dichloroéthane","option_c":"Éthane","option_d":"Chlorométhane","option_e":"","option_f":"","bonne_reponse":"a","explication":"L'addition de HCl sur l'éthène donne du chloroéthane (CH3-CH2Cl), car l'atome de chlore se fixe sur l'un des carbones de la double liaison.","points":1,"type":"qcm","actif":1,"section_id":null,"ordre":0,"_debug_answer_data_type":"string","_debug_answer_data_preview":"{\"correct\": \"a\", \"options\": {\"a\": \"Chloroéthane\",

alcènes.","option_a":"Vrai","option_b":"Faux","option_c":"","option_d":"","option_e":"","option_f":"","bonne_reponse":"b","explication":"La formule CnH2n+2 correspond aux alcanes, tandis que les alcènes ont la formule CnH2n.
