Question

Assertion :All the hydrogen atoms in $C{H}_2=C=C{H}_2$ lie in one plane. Reason: All the carbon atoms in it are $s{p}^2$ hybridized.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is D Both Assertion and Reason are incorrect

The two hydrogen atoms on first carbon and the two H-atoms on the third carbon atom lie in perpendicular planes.

The central carbon atom is $sp$-hybridized while terminal carbon atoms are $s{p}^2$-hybridized.
