(a)
Interpretation:
The Lewis structure of given molecule is to be drawn.
Concept introduction:
Lewis structure is a representation of a molecule which shows shared and unshared pair of electrons. It is helpful to determine the shape of a molecule.
(a)
Answer to Problem 35A
Explanation of Solution
Nitrogen has five valence electrons. Each electron is shared by each bromine atom and two electrons are left unshared. There will be 3 lone pair each on the Br atom because Br atoms have total of 7 valence electrons and only 1 electron is involved in bonding.
(b)
Interpretation:
The Lewis structure of given molecule is to be drawn.

(b)
Answer to Problem 35A
Explanation of Solution
Fluorine has seven valence electrons and hydrogen has one valence electron. So, both share one electron with each other to complete doublet of hydrogen and octet of fluorine. Also, there will be 3 lone pair of electrons on F atom.
(c)
Interpretation:
The Lewis structure of given molecule is to be drawn.

(c)
Answer to Problem 35A
Explanation of Solution
Carbon has four valence electrons. Each electron is shared by one bromine atom and no electrons are left unshared. There will be 3 lone pair each on the Br atom because Br atoms have total of 7 valence electrons and only 1 electron is involved in bonding.
(d)
Interpretation:
The Lewis structure of given molecule is to be drawn.

(d)
Answer to Problem 35A
Explanation of Solution
Carbon has four valence electrons. One electron of carbon is shared with hydrogen to complete its doublet and carbon shares three electrons with other carbon to complete octet and no electrons are left unshared.

- 4. a) Give a suitable rationale for the following cyclization, stating the type of process involved (e.g. 9-endo-dig), clearly showing the mechanistic details at each step. H CO₂Me 1) NaOMe 2) H3O® CO₂Mearrow_forward2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.arrow_forwardChem 141, Dr. Haefner 2. (a) Many main group oxides form acidic solutions when added to water. For example solid tetraphosphorous decaoxide reacts with water to produce phosphoric acid. Write a balanced chemical equation for this reaction. (b) Calcium phosphate reacts with silicon dioxide and carbon graphite at elevated temperatures to produce white phosphorous (P4) as a gas along with calcium silicate (Silcate ion is SiO3²-) and carbon monoxide. Write a balanced chemical equation for this reaction.arrow_forward
