Final Answer:
The Lewis structures for the given molecules are as follows:
(a) SiH₄ - Each hydrogen atom is bonded to the silicon atom.
(b) CO - Carbon is double-bonded to oxygen.
(c) SF₂ - One sulfur atom is double-bonded to one fluorine atom, and another fluorine atom is singly bonded to the sulfur atom.
(d) H₂SO₄ - Two hydrogen atoms are singly bonded to each oxygen atom, one oxygen atom is double-bonded to the sulfur atom, and two oxygen atoms have single bonds with the sulfur atom.
(e) ClO₂ - Chlorine is double-bonded to one oxygen atom, and another oxygen atom is singly bonded to chlorine.
(f) NH₂OH - One nitrogen atom is singly bonded to two hydrogen atoms and double-bonded to an oxygen atom, while the other oxygen atom is singly bonded to the nitrogen atom.
Step-by-step explanation:
SiH₄, silicon tetrahydride, consists of a silicon atom bonded to four hydrogen atoms. Silicon has four valence electrons, while each hydrogen atom contributes one electron, resulting in a total of eight valence electrons. To satisfy the octet rule, each hydrogen atom forms a single bond with silicon, utilizing all eight valence electrons.
CO, carbon monoxide, comprises a carbon atom double-bonded to an oxygen atom. Carbon has four valence electrons, and oxygen has six. In CO, carbon forms a double bond with oxygen, sharing two electrons each, fulfilling the octet rule for both atoms.
SF₂, sulfur difluoride, involves a sulfur atom double-bonded to one fluorine atom and singly bonded to another fluorine atom. Sulfur has six valence electrons, and each fluorine contributes one. A double bond between sulfur and one fluorine atom and a single bond with another fluorine atom complete the octet around sulfur.
H₂SO₄, sulfuric acid, consists of two hydrogen atoms singly bonded to each oxygen atom and one oxygen atom double-bonded to the sulfur atom. The remaining two oxygen atoms form single bonds with the sulfur atom, resulting in the complete octet for all atoms.
ClO₂, chlorine dioxide, comprises a chlorine atom double-bonded to one oxygen atom and singly bonded to another oxygen atom. The double bond and single bond between chlorine and oxygen atoms satisfy the octet rule for both.
NH₂OH, hydroxylamine, involves one nitrogen atom singly bonded to two hydrogen atoms and double-bonded to an oxygen atom. The other oxygen atom forms a single bond with the nitrogen atom, fulfilling the octet rule for each atom in the molecule.
