Question

$C{H}_2=C=C{H}_2$
In molecule (allene)

• A. All three C-atoms are $s{p}^2$ hybridized
• B. Both terminal C-atoms are $s{p}^2$ hybridized while central C-atom is sp-hybridized
• C. Both terminal C-atoms are sp-hybridized whilecentral C-atom is $s{p}^2$-hybridized
• D. None of these

Answer 1

Answer: (B)

Both terminal C-atoms are $s{p}^2$ hybridized while central C-atom is sp-hybridized

Analleneis a compoundin which one carbonatom has double bondswith each of its two adjacent carbon centres. The central carbon is sp-hybridised and the two terminal carbon atoms are $s{p}^2$-hybridised.

Therefore, option (B) is correct.
