The reagent that will efficiently convert but-1-yne into hex-3-yne NaNH2, and CH3CH2I
The preparations of alkynes are very similar to those of the alkenes. The main preparative reactions generally involve the elimination of groups or ions from the molecules, resulting in the formation of the π bonds.
Dehydrohalogenation is the loss of a hydrogen atom and a halogen atom from the adjacent alkane carbon atoms that leads to the formation of an alkene. The loss of additional hydrogen and halogen atoms from the double‐bonded carbon atoms leads to alkyne formation. The halogen atoms can be located on the same carbon that is called a geminal dihalide or on adjacent carbons that is a vicinal dihalide.
Butyne is a terminal alkyne. It has acidic hydrogen which can be removed by using a strong base to convert butyne into butynide.
The reagents which can be used to remove the acidic hydrogen from butyne are NaH or NaNH2.
Butynide will then react with ethylhalide to form hexyne.
The reagents which can be used for ethylation of butynide are;
CH3CH2I or CH3CH2Cl.

An alkene can become an alcohol through a two-step chemical process called hydroboration-oxidation. Borane (BH3) is added during the hydroboration process. Cyclohexanol is produced by the hydroboration-oxidation of cyclohexene.
How does the hydroboration-oxidation technique work?In organic chemistry, the hydroboration-oxidation process is a two-stage hydration reaction that converts an alkene into alcohol. As a result, the hydroboration process transforms alkynes into aldehydes and alkenes into neutral alcohols.
Give an example of the hydroboration-oxidation reaction.The addition of borane followed by oxidation is referred to as the hydroboration-oxidation reaction.

The Hofmann elimination would be the process by which an amine is eliminated to produce alkenes. The Hofmann product, the least stable alkyl group, is created.
By treating quaternary ammonium using excessive amounts of methyl iodide, then treating the resultant chemical with silver oxide, water, as well as heat, Hofmann's elimination produces tertiary amines including alkenes. Imidazolium iodide solution is the end result of treating quaternary ammonium with too much methyl iodide. After the hydroxyl anion replaces the iodine, the alkene can be created by an elimination reaction.
As was previously said, Hofmann elimination refers to the method of converting quaternary ammonium into tertiary amines as well as alkenes.

A chemical equation must always be in balance because, according to the law of conservation of mass, mass cannot be generated or destroyed.
How to calculate the balance equation?Writing a balanced equation for the reaction is the first step. Below is an example to help:
Ca(NO3)2 + 2H2O > 2HNO3 + Ca(OH)2
By using the equation:
nA = 2 (mole of acid).
nB = 1 (mole of base)
Information gleaned from the query includes:
Ma (Acid Molarity) =?
Va (acid volume) = 20.7 mL
Mb = 0.106 Mb (Molarity of Base)
Vb = 13.1 mL (volume of base).
We can determine the acid's molarity by using the formula MaVa/MbVb = nA/nB as follows:
nA/nB = MaVa/MbVb
Ma x 20.7/ 0.106 x 13.1 = 2/1
As demonstrated below, cross multiply to express in linear form:
Ma x 20.7 = 0.106 x 13.1 x 2
Add 20.7 to both sides.
Ma = (0.106 x 13.1 x 2) / 20.7
Ma = 0.134M

According to the Dalton Law in a blend of non-reacting gases, the entire pressure will be equivalent to the total of partial pressures of the individual gases.
The pressure of H₂ gas collected in the tube will be 728.8mm Hg.
This can be calculated by:
Dalton's formula:
Ptotoal = PH2O + PH2
Given :
Ptotal = total pressure of gases = 748. 6mm Hg
PH2O = partial pressure of water = 19.8 mm Hg
PH2 = partial pressure of hydrogen = ?
Now using the formula we will calculate:
748. 6mm Hg = 19.8 mm Hg + PH2
