Which is the formula for the functional group in an amine?

Answers

Answer 1

Answer:

An 'amine' is an organic compound primarily composed of carbon(C), hydrogen(H) and nitrogen (N).

Ammonia is a molecule in which the N atom is attached to 3 H atoms, in addition there is a lone pair of electrons on the central N atom. Amines are essentially derivatives of ammonia where one of more H atoms have been replaced by an alkyl (R) or aryl(Ar) group

For example:

R-NH2 == primary amine

R2-NH == secondary amine

R3N == tertiary amine

Answer 2

Answer: The amine functional group is R-NH2, 2 or 3 hydrogen atoms have been replaced by organic groups R, forming primary amine, secondary amine and tertiary amine.

hope this helps!

the answer is ALWAYS THE SAME.

Answer:B

Explanation:

Ammonia, NH3, can be classified as a base because in a chemical reaction with an acid, ammonia will (1 point)produce hydroxide ions in solution. produce hydronium ions in solution. donate a proton and become NH2–. accept a proton and become NH4+.

Answers

Answer: Option (d) is the correct answer.

Explanation:

Bases are the electron rich species which readily accept a proton. Therefore, when ammonia is classified as a base in a chemical reaction with an acid, it readily accepts a proton to give ammonium cation.

For example, the reaction of ammonia with hydrochloric acid will be as follows.

$NH_(3) + HCl \rightarrow NH^(+)_(4) + Cl^(-)$

Thus, we can conclude that ammonia, $NH_(3)$ , will accept a proton and become $NH^(+)_(4)$ .

NH will accept a proton and become NH4+

Bases follow $B^-+H^+=BH$ , with $B^-=NH_3$ in our case.

Given the reaction at equilibrium:N2(g) + 3H2(g) -->2NH3(g) + 91.8 kJ
What occurs when the concentration of H2(g) is increased?
(1) The rate of the forward reaction increases and the concentration of N2(g) decreases.
(2) The rate of the forward reaction decreases and the concentration of N2(g) increases.
(3) The rate of the forward reaction and the concentration of N2(g) both increase.
(4) The rate of the forward reaction and the concentration of N2(g) both decrease.

Answers

If the concentration of $H_2 (g)$ is increased, the rate of the forward reaction increases and the concentration of $N_2 (g)$ decreases.

Le Chartelier principle

The principle states that reactions in equilibrium being disturbed by factors such as temperature, the concentration of species in the reaction, etc, will experience a shift in the equilibrium so as to annul the effects of the disturbance.

Thus, adding more of the reactants ( $H_2 (g)$ to the reaction will see more products being synthesized. This means more $N_2 (g)$ will be consumed and its concentration will decrease accordingly.
