Carbon and Carbon covalent bonds
Carbons are typically nice guys who like sharing their electrons with other atoms. They’re found in most places and social gatherings – cinemas, theaters, restaurants, parties, football matches, and any where nature is present. They enjoy interacting with other atoms and sometimes get really close and bond with unsuspecting passers by.
Carbons tend to like other atoms with similar electronegativity. For instance they get attracted to their own kind – creating carbon-to-carbon bonds. Sometimes they prefer distant neighbors like the hydrogen and oxygen atoms. So they can form polar covalent bonds.
But in the carbon-to-carbon bonds, they form single bonds. Single bond simply means sharing one pair of bonding electrons and is represented by one line.
