True, False, or Sometimes true

1)A bond in which one atom contributes both bonding electron is called a polyatomic covalent bond.(True)

2)Carbon forms four single covalent bonds with other atoms. (Fales)

True, False, or Sometimes true

1)A bond in which one atom contributes both bonding electron is called a polyatomic covalent bond.(True)

I think this is false. The bond in which one atom contributes both bonding electrons is called a coordinate covalent bond.

2)Carbon forms four single covalent bonds with other atoms. (Fales)

Carbon DOES form four single covalent bonds with MOST other atoms but there are instances in which it forms double bonds (with itself, oxygen, etc) and it forms triple bonds with itself. So I don't know if this statement is true or not. You be the judge of that.



Exact answer to 2) is here:

A molecule of bromine has six unshared pairs of electrons. (TRUE)

1) False. The bond in which one atom contributes both bonding electrons is called a coordinate covalent bond.

2) True, except for a few exceptions. Carbon typically forms four single covalent bonds with other atoms.

True, False, or Sometimes true

1)A bond in which one atom contributes both bonding electron is called a polyatomic covalent bond. (False)

I apologize for the incorrect previous explanation. The correct answer is false. A bond in which one atom contributes both bonding electrons is called a coordinate covalent bond.

2) Carbon forms four single covalent bonds with other atoms. (True, but with exceptions)

Carbon commonly forms four single covalent bonds with other atoms, such as in methane (CH4). However, there are instances where carbon can form double or triple bonds with other atoms, such as in ethene (C2H4) or ethyne (C2H2), respectively. So, while carbon primarily forms four single covalent bonds, there are exceptions to this rule.
