Describe the properties of alkaline earth metals. Based on their electronic arrangement, explain whether they can exist alone in
zheka24 [161]

Answer: all i know about alkaline metals is he alkaline earth metals are shiny, silvery-white, and somewhat reactive metals at standard temperature and pressure.

All the alkaline earth metals readily lose their two outermost electrons to form cations with a 2+ charge.

All of the alkaline earth metals except magnesium and strontium have at least one naturally occurring radioisotope.

Magnesium and calcium are ubiquitous and essential to all known living organisms.

What volume will 1.27 moles of helium gas occupy at stp
inna [77]

Answer:

28.45L

Explanation:

1mole of a gas occupy 22.4L at stp. This implies that 1mole of He also occupy 22.4L at stp.

Now if 1mole of He occupied 22.4L at stp, then, 1.27mol will occupy = 1.27x22.4 = 28.45L

Compound a, c8h10, undergoes nitration to give 2 products. The 1h nmr spectrum of a shows a complex five-proton multiplet at 7.2
alekssr [168]
<h3>Answer:</h3>

             Compound A is Ethylbenzene.

<h3>Explanation:</h3>

                   The structure of Ethylbenzene was elucidated and finalized based on following facts:

1)    The presence of multiplet signal ranging from δ  7.27 to 7.40 ppm confirms the presence of aromatic protons. Also the statement says that this signal is for 5 protons indicating that the benzene ring is mono substituted.

2)   The substituted group on benzene is Ethyl because the quartet for two protons shows that two protons (-CH₂-) are coupled with a CH₃ group. Hence, the ethyl group gives one quartet and one triplet signal.

3)    The chemical reaction stated in statement is Nitration reaction. Also, the alkyl group (ethyl) is ortho-para directing in nature. Hence, it will give two products i.e. 1-Ethyl-2-nitrobenzene and 1-Ethyl-4-nitrobenzene respectively.

Attached figure gives the calculated NMR spectrum of Ethylbenzene and the chemical shifts calculated are almost near to the given values. Also, the two products formed are shown.
