Question

Select correct statements about $C_3^{4-}$ ion.

• A. It reacts with $H_{2}O$ forming $C_3{H}_6$.
• B. It reacts with $H_{2}O$ forming $C_3{H}_4$.
• C. It has two sigma and two pi bonds.
• D. It has three sigma and one pi bonds.

Answer 1

Answer: (B), (C)

The correct options are
B It reacts with $H_{2}O$ forming $C_3{H}_4$.
C It has two sigma and two pi bonds.

The correct statements about $C_3^{4-}$ ion are

(B) It reacts with $H_{2}O$ forming $C_3{H}_4$

$C_3^{4-}+2H_{2}O\to C_3{H}_4+O_2+4e^{-}$

(C) It has two sigma and two pi bonds $[C=C=C{]}^{4-}$
