Name the type of organic compound from each description of the functional group: (b) group that is not polar and has a double bo
krek1111 [17]

Some of the crucial functional groups in organic compounds are the hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl groups. The formation of molecules including DNA, proteins, carbohydrates, and lipids depends heavily on these groups.

<h3>What is Function Group ?</h3>

In organic chemistry, a functional group is a collection of atoms within molecules that interact to cause predictable reactions. Functional groups include the hydroxyl, ketone, amine, and ether groups, for instance.

(b) Most double bonds, such those found in alkenes, are formed when two carbon atoms are present. In a carbonyl group, for instance, where a carbon atom and an oxygen atom are together, there are several double bonds connecting the two separate components. Sulfoxides (S=O), imines (C=N), and azo compounds (N=N) also include common double bonds.

An ion with a -2 charge has? A) one missing protein B) two missing protons c) two missing electrons D) two extra electrons
Andreyy89

Answer:

D.

Explanation:

It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).

- Hope that helps! Please let me know if you need further explanation.
