Question 22 (multiple choice worth 2 points)

(02.01h mc)
the great number and complexity of organic compounds is reflected in which of the following?

carbon has four valence electrons and can form many other molecules.

carbon is a nonreactive element which increases its stability.

carbon has the ability become stable by joining to only itself to create diverse chains.

carbon is nonpolar when combined with many different elements.

Explanation:

Carbon is a non-metal that has atomic number 6 with electronic distribution 2, 4. As there are four valence electrons so, carbon atom combines with other molecules in order to complete its octet and attain stability.

Also, a carbon atom has the property to combine with its own atoms resulting in the formation of long chains. This property of carbon atom is known as catenation.

Therefore, we can conclude that the following statements are are true about the great number and complexity of organic compounds is reflected in:

the backbone of the dna and rna compound is sugar phosphate.
