NEET BIOLOGY

Detailed explanation-1: -Assertion :Carbon has ability to form long carbon chains. Reason: Carbon has a unique property of ability to form long straight and branched chains called catenation .

Detailed explanation-2: -Carbon has the ability to bond to itself repeatedly, making long chains of carbon atoms, as well as ringed structures. These bonds can be single, double, or triple covalent bonds. Carbon readily makes covalent bonds with other elements-primarily hydrogen, oxygen, nitrogen, halogens, and several other nonmetals.

Detailed explanation-3: -Carbon has a unique property of linking with other carbon atoms to form long chains through sharing of electrons (covalent bond). Carbon forms the longest chains using catenation. Other elements like sulphur, silicon and boron also exhibits this property.

Detailed explanation-4: -Carbon binds to oxygen, hydrogen, and nitrogen covalently to form the many molecules important for cellular function. Carbon has four electrons in its outermost shell and can form four bonds. Carbon and hydrogen can form hydrocarbon chains or rings.

Detailed explanation-5: -The ability of a carbon atom to link with other carbon atoms to form long carbon chains is known as catenation. This is the reason for the presence of the vast number of organic compounds (carbon-based) in nature.
