What are Alkanes?

About Alkanes:

• Alkanes are organic compounds that consist entirely of single-bonded carbon and hydrogen atoms and lack any other functional groups.
• Alkanes have the general formula CnH2n + 2 (where n is an integer).
• Alkanes can be subdivided into three groups: the linear straight-chain alkanes,branched alkanes, and cycloalkanes.
• They show little chemical affinity for other substances and are chemically inert to most laboratory reagents.
• They are also relatively inert biologically and are not often involved in the chemistry of living organisms.
• Alkanes do, however, react with oxygen, halogens, and a few other substances under appropriate conditions.
• Reaction with oxygen occurs during combustion in an engine or furnace when an alkane is used as a fuel.
  • Carbon dioxide and water are formed as products, and a large amount of heat is released.
• They are commercially very important, being the principal constituent of gasoline and lubricating oils and are extensively employed in organic chemistry.
• Examples of alkane include methane, ethane, propane, butane, etc.

Q1: What are halogens?

Halogens are any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
