Degree of unsaturation of A= 2 double or triple bond. Identify A.
None of these
A.
Degree of unsaturation of C10H18O = 2, but it contains no double or triple bond. Hence there are two rings - one six membered as indicated by product and the other three membered which is cleaved by HCLdue to strain. Hence A has following structure.
Assertion: Cis-2-butene gives meso-2, 3-butanediol with dilute alkaline KMnO4 solution.
Reason : Dilute alkaline KMnO4 solution gives trans addition with alkenes.
