Solution

The correct option is B

Double covalent bond


Step 1:

Electrovalent compounds are those compounds in which the complete transfer of electrons takes place from one atom to another atom.

Covalent compounds are those compounds in which the atoms share one or more pairs of electrons present in their valence shells.

The general formula of an alkene is CnH2n.

Ethene contains two Carbon (C) atoms so, the value of n is two.

Ethene is an organic compound and the molecular formula of Ethene is C2H4.

It has an alkene functional group in which carbon-carbon is connected through double bond covalent.

The structure of Ethene is H2C=CH2.

Hence, the type of bond present carbon-carbon atoms in Ethene is double bond covalent.

The organic compounds containing carbon atoms have a single bond between two carbon atoms are called saturated hydrocarbons.

Alkanes are saturated hydrocarbons that contain only a single covalent bond between C and H atoms.

Example: Ethane CH3-CH3 and propane CH3-CH2-CH3 contain only single covalent bonds.

The alkynes are unsaturated hydrocarbons that contain triple bonds between the Carbon and Carbon atoms.

Example: Ethyne H-CC-H contains a triple covalent bond between the carbon atoms.

Sodium chloride NaCl and magnesium chloride MgCl2 are electrovalent compounds because both compounds are ionic in nature.

Hence, option (B) is the correct option.
