Which of the following is true of carbon?

Q. Which of the following is true of carbon?

1. It forms only polar molecules.
2. It can form a maximum of three covalent bonds with other elements.
3. It is highly electronegative.
4. It can form both polar and nonpolar bonds.

Answer: It can form both polar and nonpolar bonds.

Carbon

Carbon is a very important chemical element, with a chemical symbol of C. All known life on Earth needs it. Carbon has atomic mass 12 and atomic number 6. It is a nonmetal, meaning that it is not a metal.

When iron is alloyed with carbon, hard steel is formed. Carbon in the form of coal is an important fuel.

The allotropes of carbon include graphite, one of the softest known substances, and diamond, the hardest naturally occurring substance. It bonds readily with other small atoms, including other carbon atoms, and is capable of forming multiple stable covalent bonds with suitable multivalent atoms.

Nonpolar covalent bonds are a type of chemical bond where two atoms share a pair of electrons with each other. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms i.e A polar bond is a covalent bond between two elements with differing electronegativity.

• Carbon usually forms nonpolar organic molecules.
• Carbon can form a maximum of four covalent bonds (CH4, for example).
• Carbon is not that high on the electronegativity scale.
• Carbon does form polar and nonpolar bonds. There are a ton of examples of polar and nonpolar bonds of carbon.
