Detailed explanation-1: -The bond between fluorine and chlorine is covalent. The bond is formed by sharing a pair of electrons. As fluorine is more electronegative than chlorine, the electrons are pulled closer to the fluorine atom. Therefore, fluorine holds the electrons closer.

Detailed explanation-2: -So covalent bonds can be formed between 2 non metals and ionic bonds formed between metal and non metal. So therefore, in this case, hydrogen which is a non metal, so hydrogen, which is a non metal, is most likely to form covalent bonds with chlorine, which is also a non metal.

Detailed explanation-3: -Fluorine has 7 valence electrons in its outermost shell. Hence it needs one more electron to complete its octet electronic configuration. Two fluorine atoms combine together by sharing one pair of electrons in order to attain stability. Since one pair electrons are shared the bond formed is a single bond.

Detailed explanation-4: -With other atoms, fluorine forms either polar covalent bonds or ionic bonds. Most frequently, covalent bonds involving fluorine atoms are single bonds, although at least two examples of a higher order bond exist.

Detailed explanation-5: -In chlorine an electron pair is shared between the two atoms in Cl2. This is called covalent bonding. So by sharing electrons through covalent bond formation, atoms are able to fill their valence shell and so attain a noble gas configuration.
