Classify each solvent as protic or aprotic. a. (CH3)2CHOH c. CH2Cl2 e. N(CH3)3 b. CH3NO2 d. NH3 f. HCONH2

The protic solvents are (CH3)2CHOH, NH3, and HCONH2

The aprotic solvent are CH3NO2, CH2Cl2, and N(CH3)3

Explanation:

A protic solvent is a solvent that has a hydrogen atom bound to an oxygen (O), a nitrogen (N), or fluoride (F). Generally, any solvent that contains a labile H⁺ is called a protic solvent.

a. (CH3)2CHOH

(CH3)2CHOH is a protic solvent because one of the hydrogens is bound to oxygen (O)

b. CH3NO2

CH3NO2 is an aprotic (i.e not a protic solvent) solvent because all the hydrogens are bound to carbon.

c. CH2Cl2

CH2Cl2 is an aprotic solvent because all the hydrogens are bound to carbon.

d. NH3 is a protic solvent because all the hydrogens are bound to Nitrogen (N)

e. N(CH3)3 is an aprotic solvent because all the hydrogens are bound to carbon

f. HCONH2 is a protic solvent because two of the hydrogens are bound to Nitrogen (N)

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
