Chemical reaction is the basis of life for living organisms; no organism can remain alive without the occurrence of chemical reactions.
Chemical reactions that occur in the living organisms are called biochemical reactions, these reactions are needed for the organism to grow, develop, survive and remain alive; when the chemical reactions stop the organism die.
For instance, to remain alive one has to eat. The food eaten can not be useful to the body if the digestive enzymes do not carry out chemical reactions on it and convert it to a form that can easily enter the blood where it is needed.
Answer:
alkenes
nucleophiles
electrophiles
syn
anti
syn and anti
Explanation:
Compounds that contain a carbon-carbon double bond are known as <u>alkenes</u>
Alkenes are electron rich; therefore, simple alkenes do not react with <u>nucleophiles</u> or bases, but will react with <u>electrophiles</u> or acids.
In the IUPAC system, an alkene is identified by the suffix -ene-
Addition reactions in which two parts Of a reagent are added to the same side of
a double bond are known as <u>syn </u>additions.
Addition reactions in which two parts of a reagent are added from opposite
sides of a double bond are called <u>anti</u> additions
Halogenation and halohydrin formation occur with <u>syn and anti</u> -additions.
Further explanations:
Compounds that contain a carbon-carbon single bond are known as alkanes. Compounds that contain a carbon-carbon double bond are known as alkenes. Compounds that contain a carbon-carbon triple bond are known as alkynes.
Nucleophiles are electron rich so they react with electron deficient centers while Electrophiles are electron deficient so they react with electron rich centers.
The different is that the galvanic cell converts chemical energy into the electrical energy and the electrolytic cell coverts electrical energy into chemical energy
