Concept Introduction:
Valence Shell Electron Pair Repulsion model predicts shape by inclusion of bond angles and most distant arrangement of atoms that leads to minimum repulsion. For the molecules that have no lone pairs around the central atom the bonded-atom unshared -pair arrangement is decided by the table as follows:
In order to determine the shape the steps to be followed are indicated as follows:
- 1. Lewis structure of molecule should be written.
- 2. The type electron arrangement around the central atom should be identified around the central atom. This essentially refers to determination of bond pairs and unshared or lone pairs around central atoms.
- 3. Then bonded-atom unshared -pair arrangement that can maximize the distance of electron pairs about central atom determines the shape.
For molecules that have lone pairs around central atom, lone pairs influence shape, because there are no atoms at the positions occupied by these lone pairs. The key rule that governs the molecular shape, in this case, is the extent of lone –lone pair repulsions are far greater than lone bond pair or bond pair-bond pair repulsions. The table that summarized the molecular shapes possible for various combinations of bonded and lone pairs are given as follows:

- If we have two compounds: acetone (CH₃COCH₃) and acetic acid (CH₃COOH), applying heat to them produces an aldol condensation of the two compounds. If this is correct, draw the formula for the final product.arrow_forwardIf we have two compounds: acetone (CH3COCH3) and acetic acid (CH3COOH); if we apply heat (A), what product(s) are obtained?arrow_forwardQUESTION: Fill out the answers to the empty green boxes attached in the image. *Ensure you all incorporate all 27 values (per column)*arrow_forward
- You need to make a buffer by dissolving benzoic acid and sodium benzoate in water. What is the mass of benzoic acid that you would weigh out, in mg, to create 50 mL of a buffer at pH = 4.7 that will change pH no more than 0.10 units with the addition of 0.001 moles of acid or base? Enter just the answer without the units (mg) - just the number will do!arrow_forwardDraw the formula for 3-isopropylcyclopentane-1-carbonyl chloride.arrow_forwardQUESTION: Fill out the answers to the empty green boxes attached in the image. *Ensure you all incorporate all 27 values (per column)*arrow_forward

Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
