Coloque as moléculas (A), (B), (C) e (D) em ordem crescente de peso molecular:
Dados: C: 12g/mol; O: 16g/mol; H: 1g/mol; F: 19 g/mol;
à (A) 2-fluoro-4-methylpentanoic acid
à (B) 3,5-dichlorocyclohexanone;
à (C) methyl 2-isopropil-but-3-enoate
à (D) N-tert-butyl-N-methylpentan-1-amine
Alternativa correta, letra "c".
Fórmulas moleculares:
(A): C6H11FO2 (134 g/mol)
(B): C6H8OCl2 (166,9 g/mol)
(C): C8H14O2 (142 g/mol)
(D): C10H23N (157 g/mol)
Logo, A<C<D<B (opção c)
OBS: Refaça a soma para confirmar o resultado.
