How many stereoisomers are obtained from the reaction of 3-methyl-2-butanone with each of the following organometallic reagents followed by the addition of dilute acid? name each stereoisomer. ethyllithium methylmagnesium bromide

Hey there!

Both are examples of Nucleophilic addition reaction and gives tertiary alcohol.

1  forms 2 Enantiomers namely (3S)-2,3-dimethyl-3-pentanol and its Enantiomer.

2 forms 2,3-dimethyl-2-butanol

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
