Question

Which of the following statements is a correct definition for a Bromsted-Lowry acid 1 Proton acceptor Electron pair donor Electron pair acceptor Proton donor Which of the following species is the conjugate base of the ion H3O+? H3o H2o H2o HO Which is the conjugate acid in the following reaction? Which of the following statements about acid strength is true? the stronger the acid, the further the equilibrium lies to the left. the stronger the acid, the smaller the Ka. The stronger the oc"d, the larger the pKa. The stronger the ackt the smaller the pKa. Which of the following statements about constitutional isomers if not true They have different IUPAC names. They have different physical properties. They have different chemical properties. What is the relationship between the following two compounds?

Explanation / Answer

According Bronsted-Lowy, acid is a proton donor.

So answer for 1) D

2)

Acid gives conjugate base by loosing a proton

Bases forms conjugate acid by accepting a proton

From this above information let us solve this question

H3O+ -------------> H2O + H+

So H2O is the conjugate base for H3O+ ion

3.

We have to find which molecule donated the proton

(-):CH3 + H2O <=======> CH4    + OH-

Here H2O gives the proton so H2O forms conjugate base

4.

Stronger the acid higher the dissociation (ka) so smaller the pKa

(Ka and pKa are inversely related)

5.

Constitutional isomers may have different functional isomers

Ex: CH3-O-CH3 and CH3CH2OH this two are constitutional isomers.

So B) option is not true

6) these are constitutional isomers.

In this these two alkanes are chain isomers ( constitutional isomers.)
