(a) 6 covalent bonds.
(b) 7 covalent bonds.
(c) 8 covalent bonds.
(d) 9 covalent bonds.
Solution: (b) Ethane has 7 covalent bonds.
Question 2: Butanone is a four-carbon compound with the functional group
(a) carboxylic acid.
Solution: (c) The functional group of butanone is ketone.
Question 3: While cooking, if the bottom of the vessel is getting blackened on the outside, it means that
(a) The food is not cooked completely.
(b) The fuel is not burning completely.
(c) The fuel is wet.
(d) The fuel is burning completely.
Solution: (b)While cooking, if the bottom of the vessel is getting blackened on the outside, then it means that the fuel is not burning completely.
Question 4: Explain the nature of the covalent bond using the bond formation in CH3Cl.
Solution: Carbon forms a bond by sharing its four electrons with other atoms. These bonds that are formed by sharing electrons are known as covalent bonds. In this bonding, both atoms share the valence electrons. Here, carbon requires 4 electrons to complete its octet and each hydrogen atom requires one electron to complete its octet. Chlorine requires one electron to complete the octet. Thus, all of these atoms share the electrons. With this formation, carbon forms 3 bonds with hydrogen and one bond with chlorine.
Question 5: Draw the electron dot structures for
(a) Ethanoic acid
(a) Ethanoic acid
