Consider the Hunsdiecker reaction given below

\mathrm{RCOOAg+Br_2 \xrightarrow[Reflux]{CCl_4} R-Br+CO_2+AgBr}

What should be the order of reactivity of the above reaction if R is 1^{\circ},2^{\circ},3^{\circ} Carbon.

Option: 1

 1^{\circ}>2^{\circ}>3^{\circ}


Option: 2

3^{\circ}>2^{\circ}>1^{\circ}


Option: 3

2^{\circ}>3^{\circ}>1^{\circ}


Option: 4

2^{\circ}>1^{\circ}>3^{\circ}

As we have learnt,

The reaction mechanism involves formation of free radicals and 1carbon free radicals will react faster due to lesser steric hinderance followed by 2o and then 3o.

Therefore, option (1) is correct.
