Question

Match the intermediates given in Column I with their probable structures in Column II

Column I		Column II
(A)	Free radical	(i)	Trigonal planar
(B)	Carbocation	(ii)	Pyramidal
(C)	Carbanion	(iii)	Linear

• A. $A\to (i);B\to (iii);C\to (ii)$
• B. $A\to (ii);B\to (iii);C\to (i)$
• C. $A\to (i);B\to (i);C\to (ii)$
• D. $A\to (i);B\to (ii);C\to (iii)$

Answer 1

Answer: (C)

Column I		Column II
i	Free radical	Free radical is formed as a result of hemolytic fission and C becomes sp 2 hybridized. Shape of free radical is trigonal planar
ii	Carbocation	In carbocation, positively charged $C$ is $s{p}^2$ hybridized and shape is trigonal planar
iii	Carbonation	In carbanion, negatively charged $C$ is $s{p}^3$ hybridized with lone pair and shape Carbanion Is pyramidal
