Vedclass · Answer

(B) The structure of cyclohexa-$1,3$-diene is a six-membered ring with two double bonds at positions $1$ and $3$.$1$. Vinylic hydrogen atoms are those attached directly to the carbon atoms involved in a double bond ($sp^2$ hybridized carbons).In cyclohexa-$1,3$-diene,there are $4$ such carbon atoms,each having one hydrogen atom attached. Thus,there are $4$ vinylic hydrogen atoms.$2$. Allylic hydrogen atoms are those attached to the $sp^3$ hybridized carbon atoms adjacent to the double bond.In cyclohexa-$1,3$-diene,there are $2$ such $sp^3$ hybridized carbon atoms (at positions $5$ and $6$). Each of these carbons is bonded to $2$ hydrogen atoms. Thus,there are $2 	imes 2 = 4$ allylic hydrogen atoms.Therefore,the molecule contains $4$ vinylic and $4$ allylic hydrogen atoms.

Cyclohexa-$1,3$-diene contains . . . . . . vinylic and . . . . . . allylic hydrogen atoms?
