Answer #1

Pencilillin is the first antibiotic for the treatment of Bacterial
diseases.Its molecular formula is C16H18N2O4S

Covalent compounds formed by sharing of electrons between atoms present
in the molecule. For example NH3 [ammonia] is a covalent compound. Another example CH4 [methane]

Ionic bond is the electrostatic force of attraction between ions.The ions are formed by loss
or gain of electrons from valance shell of atoms.For example
sodium chloride [NaCl] .Here Na looses its valance electron which is gained by Cl atom ,thus
positive and negative ions formed .Thus NaCl is an ionic compound

Polyatomic ions have more than one atom in their ions
for example : OH- [hydroxide ion] ,SO42-[sulphate ion]

example for polyatomic ionic compounds are :NaOH, H2SO4 , H3PO4
[sodium hydroxide,sulfuric acid, phosphoric acid]
