Which reactions give the less substituted (Hofmann) alkene as the major product?

A2-Fluorohexane with $NaOEt$ in ethanol
B2-Iodohexane with $NaOEt$ in ethanol
C2-Chloro-2-methylbutane with $(CH X_{3}) X_{3} COK$ in $(CH X_{3}) X_{3} COH$
DHexan-2-ol with conc. $H X_{2} SO X_{4}$ at high temperature

Answer: A, C

Fluoride is a poor leaving group and gives Hofmann orientation. The bulky tert-butoxide gives the less hindered alkene 2-methylbut-1-ene. 2-Iodohexane with small ethoxide follows Saytzeff to give hex-2-ene, and acid dehydration (E1) gives the more stable hex-2-ene major. Statements 1 and 3 are correct.
