Answer:check explanation and attached file/picture
Explanation:
Alkynes are hydrocarbons and they are very acidic because of hybridization effect(the more acidic the s-character is, the more acidic it is going to be).
The reaction of 1-hexyne with sodium amide in liquid ammonia is a form of deprotonation 'reaction' to form acetylide. Due to the acidic nature of the terminal hydrogen atom, terminal alkynes do form metallic derivatives by the replacement of the terminal hydrogens. The equation of Reaction is given below.
C6H10 + NaNH2( in liquidNH3) ------------> C6H9Na + H-NH2.
The acetylide is a bae and a very good nucleophile.
The reaction is then followed by the addition of 1-bromobutane. This reaction is used for the production of longer chain alkynes. The equation of Reaction is attached in the picture.
Answer:
A = shielding.
Explanation:
The addition of electron causes the atomic size increase from top to bottom due to increase in atomic number.
As the atomic number increased one more electron is added and because of this electron on more electronic shell is added. Thus the electron become more away from the nucleus as many of other electrons are present in the way from nucleus to the outer electrons.
The hold of nucleus becomes weaker. Although nuclear charge is also increased but at the same time other electrons shield the respective electrons. So effective nuclear charge is weaker than the actual nuclear charge.
Because of this shielding it is easy to remove the electrons or we can say ionization energy decreases.
<u>Answer:</u>
He should have put the glass in a broken glass bin
<u>Explanation:</u>
Putting broken glasses in the trash can or the dust bin can be hazardous to the workers working at local recycling center as the pieces might hurt them. Instead, he should have thrown the broken beaker in a separate glass bin or should have wrapped properly in paper so that it won't hurt anyone.
Also, glasses have a high melting point and therefore it is not recyclable. Hence, it should be trashed separately.
Answer:
Neutrons play no role in the net charge of an atom, so you can ignore them here.
Proton = 7
Electron = 10
Net Charge = 7 - 10
= -3
Again,
Proton = 3
Electron = 2
Net Charge = 3 - 2
= 1
Answer:
Observe the other planet throughout the year. Look at the environment when the season changes to see what changes in the environment.
