(a)
Interpretation:
To analyse the more electronegative element between H and Cl.
Concept Introduction:
Electronegativity is defined as the tendency to attract shared pair of electrons in a molecule.
A covalent bond involves sharing of two electrons between two atoms. When the atoms are of same element the bonding pair is equally shared by two atoms e.g.
But when two bonded atoms are from different elements then, the bonding pair is not equally shared.e.g

Interpretation:
To analyse the more electronegative element between n and O.

Draw the Lewis structure for each.arrow_forward2-98 Explain how the ionization energy of atoms changes when proceeding down a group of the Periodic Table and explain why this change occurs.arrow_forward3-67 Why does nitrogen have three bonds and one unshared pair of electrons in covalent compounds?arrow_forward
- 3-77 Ozone, O3, is an unstable blue gas with a characteristic pungent odor. In an ozone molecule, the connectivity of the atoms is OOO and both OO bonds are equivalent. (a) How many valence electrons must be present in an acceptable Lewis structure for an ozone molecule? (b) Write two equivalent resonance contributing structures for ozone. Be certain to show any positive or negative charges that may be present in your contributing structures. By equivalent contributing structures, we mean that each has the same pattern of bonding. (c) Show by the use of curved arrows how the first of your contributing structures may be converted to the second. (d) Based on your contributing structures, predict the OOO bond angle in ozone.

It is sold for this purpose under several trade names, including Perciene®. Does this molecule have polar bonds? Is it a polar molecule? Does it have a dipole?arrow_forward3-68 Draw a Lewis structure of a covalent compound in which nitrogen has: (a) Three single bonds and one unshared pair of electrons (b) One single bond, one double bond, and one unshared pair of electrons (c) One triple bond and one unshared pair of electronsarrow_forward
- 3-78 Nitrous oxide, N20, laughing gas, is a colorless, nontoxic, tasteless, and odorless gas. It is used as an inhalation anesthetic in dental and other surgeries. Because nitrous oxide is soluble in vegetable oils (fats), it is used commercially as a propellant in whipped toppings Nitrous oxide dissolves in fats. The gas is added under pressure to cans of whipped topping. When the valve is opened, the gas expands, thus expanding (whipping) the topping and forcing it out of the can. (a) How many valence electrons are present in a molecule of N20? (b) Write two equivalent contributing structures for this molecule. The connectivity in nitrous oxide is NNO.
