Give the best description of the regioselectivity and stereospecificity in the oxymercuration of an alkene. anti-Markovnikov ori
entation with anti-addition Markovnikov orientation with anti-addition Markovnikov orientation with both syn- and anti-addition anti-Markovnikov orientation with syn-addition Markovnikov orientation with syn-addition
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.
Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.
