If the carbon atom of hydrocarbon is bonded to less than 4 other atoms, the hydrocarbon is considered
a. aromatic
b. diluted
c. saturated
d. unsaturated

Answer : The correct option is, (D) unsaturated

Explanation :

As the organic compounds are classified into two categories which are acyclic (aliphatic) and cyclic (aromatic) compounds.

Acyclic compounds are also classified into two categories which are saturated and unsaturated compounds.

Saturated hydrocarbon : These are the compounds which containing single bonds between the carbon-carbon atoms. In saturated compounds, there are more number of hydrogen bonded with the carbon atom.

Unsaturated hydrocarbon : These are the compounds which containing double and triple bonds between the carbon-carbon atoms. In unsaturated compounds, there are less number of hydrogen bonded with the carbon atom.

Aromatic : Aromatic compounds are the type of an unsaturated compounds but it is not necessary that the unsaturated compounds are aromatic. It is a compound which containing the electrons and all the electrons are in conjugation.

Hence, if the carbon atom of hydrocarbon is bonded to less than 4 other atoms, the hydrocarbon is considered as unsaturated.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
