Option 1: Most carbon compounds are good conductors of electricity.

This statement is not correct. Carbon compounds, also known as organic compounds, typically do not conduct electricity well. This is because they usually contain covalent bonds, where electrons are shared between atoms rather than freely moving to conduct electricity. While there are some exceptions, such as carbon-based materials like graphene, most organic compounds are insulators or have low electrical conductivity.

Option 2: Bonding in organic compounds is covalent.

This statement is correct. Organic compounds primarily form covalent bonds, which involve the sharing of electrons between atoms. Covalent bonding gives carbon compounds their unique properties and is a fundamental concept in organic chemistry.

Option 3: Graphite is used as a lubricant.

This statement is correct. Graphite, which consists of layers of carbon atoms arranged in a hexagonal lattice, has a slippery texture due to weak interlayer forces. This makes it an excellent lubricant, reducing friction and allowing smooth movement between surfaces.

Option 4: Diamond is an allotrope of carbon.

This statement is correct. Allotropes are different forms of an element that have distinct physical properties. Diamond is an allotrope of carbon characterized by its hardness, high melting point
