Question

(a) What is an alkyl group?
(b) Give the names of any three alkyl groups. How are they formed?

Answer 1

1. An alkyl group is the group that lacks one of the hydrogen atoms of an alkane.
2. The names of three alkyl groups are methyl (−CH₃), ethyl (−C₂H₅) and butyl (−C₄H₉). They are formed by the removal of one hydrogen atom each from methane (CH₄), ethane (C₂H₆) and butane (C₄H₁₀) respectively.
