Answer 1

Classes of Compounds and Naming of Substances

In the given question, we are asked to determine the classes of compounds and provide the names and formulas of two isomers for each substance. Let's analyze each substance and determine their classes and isomers.

A: C4H9OH - This substance has the molecular formula C4H9OH, which indicates that it belongs to the class of alcohols. - Two isomers of C4H9OH are: 1. Butan-1-ol (n-butanol): CH3CH2CH2CH2OH 2. Butan-2-ol (sec-butanol): CH3CH(OH)CH2CH3

B: C2H5CooC2H5 - This substance has the molecular formula C2H5CooC2H5, which indicates that it belongs to the class of esters. - Two isomers of C2H5CooC2H5 are: 1. Ethyl ethanoate (ethyl acetate): CH3COOC2H5 2. Ethyl propanoate: CH3CH2COOC2H5

C: CH3CH(NH2)-COOH - This substance has the molecular formula CH3CH(NH2)-COOH, which indicates that it belongs to the class of amino acids. - Two isomers of CH3CH(NH2)-COOH are: 1. Alanine: CH3CH(NH2)COOH 2. Beta-alanine: CH3CH2CH(NH2)COOH

D: CH3C(O)CH3HCOOH - This substance has the molecular formula CH3C(O)CH3HCOOH, which indicates that it belongs to the class of carboxylic acids. - Two isomers of CH3C(O)CH3HCOOH are: 1. Propanoic acid: CH3CH2COOH 2. Acetic acid: CH3COOH

E: HCOOH - This substance has the molecular formula HCOOH, which indicates that it belongs to the class of carboxylic acids. - Two isomers of HCOOH are: 1. Formic acid: HCOOH 2. Methanoic acid: HCOOH

Please note that the isomers provided are just examples, and there may be more possible isomers for each substance.
