The number of hyperconjugative structures of the ethyl cation, $CH X_{3} CH X_{2} X^{+}$ , is (equal to the number of alpha hydrogens on the sp3 carbon attached to the cationic carbon):

A6
B3
C2
D1

Answer: B

The cationic carbon is attached to one

CH X_{3}

group carrying 3 alpha hydrogens. Number of hyperconjugative structures = 3.
