Reactivity of R-X depends on bond length. More be the bond length, easier for the R-X to go for dehydrohalogenation. Thus, correct order is: R- I >R- Br >R- Cl >R- F

Q. Reactivity order of halides for dehydrohalogenation is :-

$R - F > R - Cl > R - B r > R - I$

$R - I > R - B r > R - Cl > R - F$

$R - I > R - Cl > R - B r > R - F$

$R - F > R - I > R - B r > R - Cl$

Reactivity of $R - X$ depends on bond length.

More be the bond length, easier for the $R - X$ to go for dehydrohalogenation.

Thus, correct order is :

$R - I > R - B r > R - Cl > R - F$

Q. Reactivity order of halides for dehydrohalogenation is :-

R−F>R−Cl>R−Br>R−I

R−I>R−Br>R−Cl>R−F

R−I>R−Cl>R−Br>R−F

R−F>R−I>R−Br>R−Cl

Reactivity of R−X depends on bond length. More be the bond length, easier for the R−X to go for dehydrohalogenation. Thus, correct order is : R−I>R−Br>R−Cl>R−F

$R - F > R - Cl > R - B r > R - I$

$R - I > R - B r > R - Cl > R - F$

$R - I > R - Cl > R - B r > R - F$

$R - F > R - I > R - B r > R - Cl$

Reactivity of $R - X$ depends on bond length.

More be the bond length, easier for the $R - X$ to go for dehydrohalogenation.

Thus, correct order is :

$R - I > R - B r > R - Cl > R - F$
