Homework Answers
Ans. Option c
Ordinary alkane typically do not absorbs in the anywhere uv /visible region .The organic molecule which typically contains electrons in pi or non bonding orbital absorbs in uv/vis region .All the given molecule except Butane have pi bonding electrons (C=C)
Butane has no pi or non bonding electrons so the value corresponds to it will be less among all.
