ChemistrySingle correct+4 / -1Question 54 of 90

For the compounds $\ce{CH3Cl}$ , $\ce{CH3Br}$ , $\ce{CH3I}$ and $\ce{CH3F}$ , the correct order of increasing C-halogen bond length is :

\ce{CH3F < CH3Cl < CH3Br < CH3I}

\ce{CH3F < CH3Br < CH3Cl < CH3I}

\ce{CH3F < CH3I < CH3Br < CH3Cl}

\ce{CH3Cl < CH3Br < CH3F < CH3I}

Answer and worked solution

Official answer: A

C-X bond length grows with the halogen's size: $\ce{CH3F < CH3Cl < CH3Br < CH3I}$ .
