There are so many such compounds as H2O, HF.
The hydrochloric acid molecule has a polar covalent bond between hydrogen and chlorine atoms.
Extra-molecular polar bonds
Hydrogen is an element, not a bond. It can form bonds, which are usually covalent, but an ionic bond with hydrogen is possible, for example, lithium hydride is an ionic compound. While this, like every compound, does have its own distinctive features, I would not call it a special form of ionic bond.
hydrogen, polar
No, the compound CH3CH2CH2CH3 (butane) does not have any hydrogen atoms bonded to electronegative atoms such as oxygen, nitrogen, or fluorine. Therefore, it cannot form hydrogen bonds.
The hydrochloric acid molecule has a polar covalent bond between hydrogen and chlorine atoms.
polar covalent
Hydrogen and Fluorine form the most polar bond H-F, the difference of electronegativities is 1.9.
Because they form strong Hydrogen Attraction bond
yes

Yes. Sulfur (S) and hydrogen (H) will form a polar covalent bond.
polar covalent
Chlorine cannot form a hydrogen bond only Nitrogen, Oxygen, and Flourine can
They do not have any bonds in common. Calcium and chlorine atoms form an ionic bond and hydrogen and nitrogen form a polar covalent bond.
