Question

Column I		Column II
A		p	Radical anion
B		q	Carbanion
C		r	Triplet carbene
D		s	Singlet carbene
E		t	Carbocation

• A. A= t ,B= s ,C= p ,D= r ,E= p
• B. A=p ,B= s,C= r ,D= p ,E=p
• C. A= t ,B= p,C= s ,D= r ,E=p
• D. A= s ,B= r,C= p ,D= t ,E=p

Answer 1

Answer: (D)

$(a\to s),(b\to r)$
$(c\to p)($ Radical anion, $RC\dot{C}=CH-\stackrel{\ddot{\ominus }}{C}-R)$
$(d\to t)$
$(e\to p)(E1cB$ mechanism)
