Question

3. Which of the following possess highest bond length? 1) CHF 2) CH3C1 3) CH3Br 4) CH3​

Answer 1

Explanation:

C-halogen bond length totally depends on the electronegativity difference between Carbon and halogen. The more the difference is, the less is the bond length. The electronegativity order of halogens is I<Br<Cl<F. Hence, the correct order of increasing C-halogen bond length ch3f<ch3cl<ch3br<Ch3i
