Substituting a hydrogen atom with a halogen in a hydrocarbon:
- the single bond remains single. A is wrong.
- the bond with Hydrogen is as strong as with a Halogen. C is wrong
- a hydrocarbon is saturated if there is no double bond. We do not know that so D is wrong.
- carbon will always have four valence electrons. E is wrong.
By elimination, the correct answer is B. The boiling point of the new compound increases.

Answer:
234 KJ ≡ 55.887 Kcal
Explanation:
∴ J ≡ Kg/m².s² ≡ N.m = 0.2389 cal
∴ cal = 4.187 J
⇒ 234 KJ * ( 1000 J / KJ ) * ( cal / 4.187 J ) * ( Kcal / 1000 cal ) = 55.887 Kcal
