<u>Answer:</u> Bromine atom will have 7 valence electrons.
<u>Explanation:</u>
Valence electrons are defined as the electrons which are present in the outermost shell of an atom known as valence shell.
Bromine is the 35th element of the periodic table having 35 number of electrons.
The electronic configuration of bromine is
The valence shell for this element has n = 4. So, the number of electrons that are present in orbitals having n = 4 are 7.
Thus, bromine atom will have 7 valence electrons.
Answer : There are multiple characteristics which are different between silver (Ag) and mercury (Hg).
Ag is solid at room temperature while Hg is liquid.
Ag is not so toxic as compared to Hg.
Ag can be tarnished but Hg can not be tarnished.
Mercuric chloride dissolves in ammonia whereas silver chloride does not dissolves.
Answer:
Compound A: Benzoyl chloride
Compound B: Benzaldehyde - (tBuO)₃Al complex
Compound C: Benzaldehyde
Compound D: Benzyl alcohol
Explanation:
The lithium tri-tert-butoxyaluminum hydride that the first student used is a milder reagent than LAH and will stop reacting at the aldehyde.
The LAH that the second student used is much more reactive and will continue to reduce the benzoic acid as far as possible, going all the way to the alcohol.
