The arrangement of (CH3)3C—, (CH3)2CH—, CH3CH2 — when attached to benzene or unsaturated group in increasing order of inductive effect is GENERAL ORGANIC CHEMISTRY
A.(CH3)3 C — < (CH3)2 CH— < CH3CH2—
B.CH3CH2 — < (CH3)2 CH — < (CH3)3 C —✓ Correct
C.(CH3)2CH — < (CH3)3 C— < CH3CH2 —
D.(CH3)3C — < CH3CH2 — < (CH3)2 CH —
Explanation
Presence of Methyl group increases the inductive effect hence with the increase in the number of methyl groups the inductive effect increases.
