An organic compound that contains a nitrogen atom bonded to one, two, or three different carbon atoms is a(n) ether. amine. ester. ketone

The correct answer is amine.

Explanation:

All the given options are a type of functional groups. These are defined as the groups which change the

For the given choices:

Ether: These functional group has single bonded oxygen t two carbon atoms. This group is written as where R and R' can be alkyl or aryl groups.

Amine: In this functional group, nitrogen is bonded to carbon atom by single bond. This nitrogen atom can be bonded to one, two or three carbon atoms and are named as primary (1°), secondary (2°) and tertiary (3°) compounds respectively. They are written as respectively.

Ester: In this functional group, two oxygen atoms are present with a carbon atom. One oxygen atom is single bonded to carbon atom and other one is doubly bonded to it. It is written as where  R and R' can be alkyl or aryl groups.

Ketone: In this functional group, one oxygen and one carbon atom is present. The oxygen atom is doubly bonded to carbon atom and the carbon atom is further joined to two alkyl or aryl groups. This is written as

Hence, the correct answer is Amine.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
