Science : Ch 04 – Carbon and its Compounds

A molecule of ammonia (NH₃) has only single bonds. The atomic number of N is 7. Its electronic configuration is ȷ2, Ǩȸ so it needs 3 more electrons to complete its octet.

Carbon always forms covalent compounds by sharing its electrons with other at atoms.The two electrons shared by the atoms are attracted to the nucleus of both the atoms.

Reaction between an acid and an alcohol results in the formation of ester, and the reaction is named as esterification.

Pencil lead is formed of graphite. Graphite is an allotropic form of carbon in which each carbon atom is joined to three others, forming layers

Denatured alcohol is the ethyl alcohol which has been made unfit for drinking purpose by adding small amount of poisonous substance like methanol, pyridine, etc.

Cyclobutane is a cyclic hydrocarbon consisting of four carbon atoms where each carbon atom is attached to the two other carbon atoms and two hydrogen atoms.

Catenation is the property of self-linking of an element by which an atom combines with the other atoms of the same element to form long chains
