Identify the correct molecular formula of pentanol?

 Pent means five and ‘ol’ means alcohol. 

 Among the given options option (a) only having an alcohol in it and the structure of pentanol is as follows. $\\$ <img  src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/49958e81-db72-4f79-bc23-e66afb99274f4723960031362902939.png"/>

 What are the functional groups present in the given molecule. $\\$<img  src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/87994236-863a-42e0-afa8-3aea591157fb8635221801734640633.png"/>

 We have to watch carefully the molecule to know about the functional groups present in it.

 The given molecule is as shown below. In the given molecule there are two functional groups and they are secondary amine and an aldehyde.$\\$ <img  src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/4276520e-2317-4fa4-b53c-21cf7bef696c6470768395674477775.png"/>

 On Ozonolysis of Acetylene what are the products going to form and find the functional groups present in the product.

 The molecule which has triple bonds will undergo ozonolysis and forms aldehyde as the product.

 The chemical reaction of ozonolysis of acetylene is as shown below. On ozonolysis of acetylene the product is Glyoxal and it contains aldehyde functional groups in it. $\\$ <img  src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/1d646bde-1594-42fa-9408-c9b4e3558adf7553156565734254736.png"/>

 Find which pair of chemicals forms the amide bond through condensation reaction.

 Amide bond is going to form by amine and carboxylic acid.

 The condensation of an amine and a carboxylic acid forms an amide bond and we can see this in the following chemical reaction. $\\$ <img  src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/27ee9fcd-66e5-48ba-9fd8-9afd2bd3db924133511662338262695.png"/>

 Chlorofluorocarbons are reasonable for the depletion of the ozone layer and they are released by the air coolers and refrigerators. Find the functional groups which causes the depletion of the ozone layer present in Chlorofluorocarbons and the mechanism which involves.

 Chlorofluorocarbons are going to release from air coolers and refrigerators. In sunlight chlorofluorocarbons dissociates and forms free radicals. 

 Chlorofluorocarbons contain halides when they are exposed to sunlight they dissociate and form free radicals. The formed free radicals deplete the ozone layer through a chain mechanism.
