The correct order of the C — F bond distance among the given compounds: CH3F > CH2F2 > CHF3> CF4 With increase in number of fluorine atoms on the geminal carbon, the electrostatic interaction and thus, the bond strength between carbon and fluorine increases and thus, the bond length (C — F) decreases

Q. What will be the correct order of the $C — F$ bond distance among the following?
$C H F_{3}, C F_{4}, C H_{3} F$ and $C H_{2} F_{2}$

$C H_{3} F < C H_{2} F_{2} < C H F_{3} < C F_{4}$

$C H_{2} F_{2} > C H_{3} F > C H F_{3} > C F_{4}$

$C H_{3} F > C H_{2} F_{2} > C H F_{3} > C F_{4}$

$C H_{3} F > C H F_{3} > C F_{4} > C H_{2} F_{2}$

Q. What will be the correct order of the C—F bond distance among the following? CHF3​,CF4​,CH3​F and CH2​F2​

CH3​F<CH2​F2​<CHF3​<CF4​

CH2​F2​>CH3​F>CHF3​>CF4​

CH3​F>CH2​F2​>CHF3​>CF4​

CH3​F>CHF3​>CF4​>CH2​F2​

Q. What will be the correct order of the $C — F$ bond distance among the following?
$C H F_{3}, C F_{4}, C H_{3} F$ and $C H_{2} F_{2}$

$C H_{3} F < C H_{2} F_{2} < C H F_{3} < C F_{4}$

$C H_{2} F_{2} > C H_{3} F > C H F_{3} > C F_{4}$

$C H_{3} F > C H_{2} F_{2} > C H F_{3} > C F_{4}$

$C H_{3} F > C H F_{3} > C F_{4} > C H_{2} F_{2}$
