Question

What is the hybrid state of carbon in ethyne, graphite and diamond?

• A. $sp^{2},sp,sp^{3}$
• B. $sp,sp^{2},sp^{3}$
• C. $sp^{3},sp^{2},sp$
• D. $sp^{2},sp^{3},sp$

Answer 1

Answer: (B)

$sp,sp^{2},sp^{3}$

Answer 2

: In ethyne, $H - C \equiv C - H;$ C is sp hybridized.

In graphite, one C atom is attached to 3 other C atom which are $sp^{2}$hybridized

In diamond, one C atom is attached to 4 other C atoms which are $sp^{3}$hybridized.
