Question

Which of the following compounds has the most deshielded protons?A) CH3ClB) CH3IC) CH3BrD) CH4

Answer 1

Given :

Some compounds :

$A)\ CH_3Cl\ B)\ CH_3I\ C)\ CH_3Br\ D)\ CH_4$ .

To Find :

Which of the following compounds has the most deshielded protons .

Solution :

Deshielded means nucleus whose chemical shift has been increased due to removal of electron density, magnetic induction, or other effects .

In simple words deshielding means the ability to shift protons .

Now , among Cl , I , Br and H . Cl is the most electron negative .

Therefore , deshielding will be more in $CH_3Cl$ .

Hence , this is the required solution .
