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

The compound with the presence of most deshielded protons has been . Thus, option A is correct.

Diesheilded protons have been explained as the shift in the protons of the central atom with the bonding to a more electronegative element.

The electronegative element has been possessing the negative charge and is attracted to the positive charge.There has been a shift in the protons in the sample that has been resulted in the de-shielded protons.

In the given compounds, the anions bonded to the methyl groups are Cl, C, Br, and H. Among the following, the most electronegative atom has been chlorine.

Thus, the molecule of has been consisted of the most de-shielded protons. Thus, option A is correct.

Given :

Some compounds :

.

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 .

Hence , this is the required solution .

that's what i got you can count the number of atoms
