Card 1Unique nature of carbon

Why does carbon form such a large number of compounds?

Answer

Carbon has atomic number 6 and four electrons in its valence shell. It forms four covalent bonds to complete its octet. Carbon also shows catenation, can form single, double, and triple bonds, and sho

Card 2Unique nature of carbon

What is catenation?

Answer

Catenation is the property of atoms of an element to link with one another by stable covalent bonds to form straight chains, branched chains, or rings. Carbon shows this property to the maximum extent

Card 3Unique nature of carbon

What is tetravalency of carbon?

Answer

Carbon has four electrons in its valence shell and forms four covalent bonds to achieve a stable octet. This is called tetravalency. Example: methane, CH4, has four single covalent bonds around carbon

Card 4Introduction to organic chemistry

What is the modern definition of organic chemistry?

Answer

Organic chemistry is the branch of chemistry dealing with the study of hydrocarbons and the compounds which could be thought of as the derivatives of hydrocarbons.

Card 5Classification of compounds

Are all carbon compounds organic?

Answer

No. Carbon compounds such as CO, CO2, COCl2, and SiC are of different nature and are not regarded as organic compounds.

Card 6Hydrocarbons

What are hydrocarbons?

Answer

Hydrocarbons are organic compounds made up of carbon and hydrogen atoms only. They are considered the parent compounds of many other organic compounds.

Card 7Hydrocarbons

Classify hydrocarbons based on bonding.

Answer

Saturated hydrocarbons contain only single bonds and include alkanes. Unsaturated hydrocarbons contain double bonds or triple bonds and include alkenes and alkynes.

Card 8Alkanes

What is the general formula of alkanes?

Answer

General formula of alkanes: C_nH_{2n+2} [n = number of carbon atoms (integer 1,2,3,...)]
