Question

Which of the following haloalkanes has the shortest $C-X$ bond length?

• A. $C{H}_{3}F$
• B. $C{H}_{3}Cl$
• C. $C{H}_{3}Br$
• D. $C{H}_{3}I$

Answer 1

The correct option is A $C{H}_{3}F$

As we move down the group, the covalent radius of the halogens increase. Hence, the bond length increases. Thus, $C-F$ has the shortest $C-X$ bond length.
