c) II and III only
d) III and IV only

Ed · Answer

A frequência de absorção na espectroscopia infravermelha é influenciada por vários fatores. No caso da pergunta, os fatores que influenciam a frequência de absorção são:

I- A massa dos átomos envolvidos na ligação química.
II- A força da ligação química.
III- A hibridização dos átomos envolvidos na ligação química.
IV- A presença de ressonância na molécula.

Portanto, a alternativa correta é a letra a) I, II, III e IV.
