Hydrocarbons which contain only single bonds are called alkanes. <span>This gives them a general </span><span>formula CnH2n</span>+<span>2. Given we are given eight carbon atoms then it should be that it would have 2(8)+2 = 18 hydrogen atoms. Therefore, the statement is true.</span>
Answer:

Explanation:
:)
It is soluble in water and slightly soluble in ethanol.
