Following are the two reasons.

They can figure out how the preparations collected in DNA help your body to perform properly. They can use DNA to make modern medicines or genetically transform crops to be resistant to insects. Strawberries are a very marketable horticultural crop. They do experience from disease and insect attacks, are responsive to heat and cold and prefer a comparatively close range of soil types for best production.

The study of strawberry DNA may provide the plant breeder with keys to thriving strategies to master these and many other restrictions for the strawberry product.

2.Which of the alcohols listed below would you expect to react most rapidly with PBr3?A)CH3CH2CH2CH2CH2CH2OHB)(CH3CH2)2CH(OH)CH2

Gnoma [55]

Answer:

A) CH3CH2CH2CH2CH2CH2OH

Explanation:

For this question, we have the following answer options:

A) CH3CH2CH2CH2CH2CH2OH

B) (CH3CH2)2CH(OH)CH2CH3

C) (CH3CH2)2CHOHCH3

D) (CH3CH2)3COH

E) (CH3CH2)2C(CH3)OH

We have to remember the reaction mechanism of the substitution reaction with $PBr_3$ . The idea is to generate a better leaving group in order to add a "Br" atom.

The $PBr_3$ attacks the "OH" generation new a bond to P (O-P bonds are very strong), due to this new bond we will have a better leaving group that can remove the oxygen an allow the attack of the Br atom to generating a new C-Br bond. This is made by an Sn2 reaction. Therefore we will have a faster reaction with primary substrates. In this case, the only primary substrate is molecule A. So, "CH3CH2CH2CH2CH2CH2OH" will react faster.

See figure 1

I hope it helps!
