Question

Wht is tert butyl or sec butyl mean

Answer 1

Answer:

The second isomer of butane, isobutane, can also connect in two ways, giving rise to two additional groups:

If it connects at one of the three terminal carbons, it is isobutyl: (CH3)2CH−CH2− (fully systematic name: 2-methylpropyl)

If it connects at the central carbon, it is tertiary butyl, tert-butyl or t-butyl: (CH3)3C− (fully systematic name: 1,1-dimethylethyl)
