The rules of IUPAC followed for hydrocarbon are
a) We will first find out the longest chain of carbon in the given organic compound including triple bond
the root name will be "hex" as number of carbon atoms in longest chain is six.
b) The triple bond will be assigned minimum number locant. the locant will be 2 .
The primary suffix will be "yne"
hence
hex-2-yne
c) we will give locant number to methyl group (present as substituent)
it will be "4"
Thus the completer IUPAC name will be
4-methylhex-2-yne or 4-methyl-2-hexyne [as given in the options]
DDT stands for Dichlorodiphenyl Trichloroethane.DDT was used in theas a pesticide Second World War to protect the troops and civilians from the spread of malaria and other diseases. <span>Today DDT is used for insect control.
</span>But DDT harms the environment and the human health.
<span>There is an evidence that links DDT with severe declines in bald eagle populations due to thinning eggshells.</span>
So, DDT is dangerous environmental pollutant because it is toxic.
Zn(s) + 2 HCl(aq) → ZnCl₂(aq) + H₂(g)
Oxidation means lose of electrons and increase of positive charge so the part which oxidized in this equation is Zn(s) because it converted to Zn²⁺ (i.e. lost two electrons)
relative humidity is a measure of how much water an air mass at a given temperature can hold.
<u>Explanation:</u>
When a quantity of air at a supplied temperature exists the highest volume of water vapor, the air is considered to be saturated. The relative humidity is the water-vapor content of the air corresponding to its content at fullness.
Relative humidity can be described as the quantity of water vapor in air at a provided temperature related to what that air could endure at that temperature. We can thus adjust the relative humidity of an air bundle by either raising or lowering the volume of water vapor in the parcel OR by boosting or reducing the temperature of the air mass.
