(a)
Interpretation : We need to identify HBr as polar or non-polar molecule.
Concept Introduction : The
(b)
Interpretation : We need to identify SiO2 as polar or non-polar molecule.
Concept Introduction : The chemical bonds can be classified as ionic bond and covalent bonds. Ionic bonds are formed between cation and anion. Here both of these are charged ions. On the contrary, covalent bond is formed by equal sharing of electrons. Further covalent bond can be classified as polar and non-polar covalent bond.
(c)
Interpretation : We need to identify NCl3 as polar or non-polar molecule.
Concept Introduction : The chemical bonds can be classified as ionic bond and covalent bonds. Ionic bonds are formed between cation and anion. Here both of these are charged ions. On the contrary, covalent bond is formed by equal sharing of electrons. Further covalent bond can be classified as polar and non-polar covalent bond.
(d)
Interpretation : We need to identify CH3Cl as polar or non-polar molecule.
Concept Introduction : The chemical bonds can be classified as ionic bond and covalent bonds. Ionic bonds are formed between cation and anion. Here both of these are charged ions. On the contrary, covalent bond is formed by equal sharing of electrons. Further covalent bond can be classified as polar and non-polar covalent bond.
(e)
Interpretation : We need to identify NI3 as polar or non-polar molecule.
Concept Introduction : The chemical bonds can be classified as ionic bond and covalent bonds. Ionic bonds are formed between cation and anion. Here both of these are charged ions. On the contrary, covalent bond is formed by equal sharing of electrons. Further covalent bond can be classified as polar and non-polar covalent bond.
(f)
Interpretation : We need to identify H2O as polar or non-polar molecule.
Concept Introduction : The chemical bonds can be classified as ionic bond and covalent bonds. Ionic bonds are formed between cation and anion. Here both of these are charged ions. On the contrary, covalent bond is formed by equal sharing of electrons. Further covalent bond can be classified as polar and non-polar covalent bond.
