For the given reaction The, total number of possible products formed by tertiary carbocation of A is _ _ _ _…

There are two tertiary carbocations possible due to rearrangement of hydride or methyl groups. Totally four structural alkene products are formed, out of which one is having chiral centre. Hence, total number of products formed through the formation of carbocation intermediate are 5.

(Total 5 products are possible through $3^{\circ }$ carbocation)
