Coach is used to activate carboxylic acids. what type of compound is formed between coach and a carboxylic acid?
MrMuchimi

The  type of compound is formed between coach and a carboxylic acid alcohol + carboxylic acid → ester + water.

How carboxylic acids are formed?

A acid is produced after the acidic hydrolysis of esters and carboxylates are produced after the basic hydrolysis of an ester.

What are the functional group of alcohol and carboxylic acid?

Alcohols contain the hydroxyl functional group and may be primary, secondary, or tertiary. Ethers are compounds with an oxygen atom bonded to 2 alkyl groups. Aldehydes and ketones contain the carbonyl functional group

Can a compound be a acid and an alcohol?

Esters are represented by the formula RCOOR', where R and R' are hydrocarbon groups. The ester, which is compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group, looks somewhat sort of a n ether and also somewhat like a carboxylic acid.

What would barium do to obtain a noble gas structure? gain 2 electrons lose 2 electrons gain 6 electrons lose 6 electrons
Tema [17]

Answer:

Lose two electrons.

Explanation:

Barium is present in group 2.

It is alkaline earth metal.

Its atomic number is 56.

Its electronic configuration is Ba₅₆ = [Xe] 6s².

In order to attain the noble gas electronic configuration it must loses its two valance electrons.

When barium loses it two electron its electronic configuration will equal to the Xenon.

The atomic number of xenon is 54 so barium must loses two electrons to becomes equal to the xenon.
