How many bonds can one carbon atom form in a compound? 1 2 4 6 It is the element which possess tetravalent property and thus form covalent compound. It is the element which possess tetravalent property and thus form covalent compound. 2 / 15 Which of he following compounds of carbon does not consist of ions? CHCl3 CaCO3 NaHCO3 Ca2C 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. 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. 3 / 15 Ester is formed by the reaction between: An acid and an alcohol An acid and a base A base and an alcohol An acid and an alkene Reaction between an acid and an alcohol results in the formation of ester, and the reaction is named as esterification. Reaction between an acid and an alcohol results in the formation of ester, and the reaction is named as esterification. 4 / 15 The property of self-linkage among identical atoms to form long chain compounds is known as: Catenation Isomerisation Superposition Halogenation 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 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 5 / 15 The ability of an atom to form bonds with other atoms of the same element.
