Question

carbon • carbon has the ability to create ____ bonds with up to __ other __ ◦ covalent bonds are very ____ and hard to break

Explanation:

1. Carbon can form covalent bonds (since it shares electrons to bond, typical of carbon's bonding nature).
2. Carbon can bond with up to 4 other atoms (carbon has 4 valence electrons, allowing it to form 4 covalent bonds to achieve octet).
3. The other entities are atoms (carbon bonds with other atoms, like H, C, etc., in these structures).
4. Covalent bonds are very strong (covalent bonds involve electron sharing, making them strong and requiring significant energy to break).

For the structures (bottom labels, from left to right):

• Left structure: A straight - chain hydrocarbon with single bonds, representing an alkane (specifically a long - chain alkane, e.g., hexane - like structure with single C - C bonds).
• Middle structure: A branched - chain hydrocarbon, also an alkane (has branched carbon chains with single C - C bonds).
• Right structure: A hexagonal ring with alternating double bonds, representing benzene (the aromatic compound with the formula \(C_6H_6\), having a delocalized pi - bond system in the ring).

Answer:

• carbon has the ability to create \(\boldsymbol{\text{covalent}}\) bonds with up to \(\boldsymbol{4}\) other \(\boldsymbol{\text{atoms}}\)
• covalent bonds are very \(\boldsymbol{\text{strong}}\) and hard to break
• Bottom left structure: \(\boldsymbol{\text{Alkane (e.g., long - chain alkane)}}\)
• Bottom middle structure: \(\boldsymbol{\text{Alkane (branched - chain alkane)}}\)
• Bottom right structure: \(\boldsymbol{\text{Benzene}}\)
