The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

<h3>What is the Grignard reagent?</h3>

The Grignard reagent is a compound that contains alkyl magnesium halide.

a) The student will be  unsuccessful to prepare a Grignard reagent from 4-bromocyclohexanol because of the -OH group that reacts with the Grignard reagent when formed.

b) The Benzenesulfonic acid does not undergo Friedel-Crafts alkylation because of the deactivation of the compound by the  carboxylic group.

c) The compound (2S, 3R)- 2,3-Dibromobutane has a specific rotation, [a]D, 0⁰ because it is a meso compound.

d) This is because, the tertiary alkyl halide is more prone to elimination reaction giving the alkene.

e) This is because, the reaction may be occurring by an SN1 mechanism and the rate determining step is the formation of the carbocation.

The atomic weight of iodine is less than the atomic weight of tellurium. However, Mendeleev listed iodine after tellurium in his
QveST [7]

Explanation :

As we know that Mendeleev arranged the elements in horizontal rows and vertical columns of a table in order of their increasing relative atomic weights.

He placed the elements with similar nature in the same group.

According to the question, the atomic weight of iodine is less than the atomic weight of tellurium. So according to this, iodine should be placed before tellurium in Mendeleev's tables. But Mendeleev placed iodine after tellurium in his original periodic table.

However, iodine has similar chemical properties to chlorine and bromine. So, in order to make iodine queue up with chlorine and bromine in his periodic table, Mendeleev exchanged the positions of iodine and tellurium.

As we know that the positions of iodine and tellurium were reversed in Mendeleev's table because iodine has one naturally occurring isotope that is iodine-127  and tellurium isotopes are tellurium-128 and tellurium-130.

Due to high relative abundance of tellurium isotopes gives tellurium the greater relative atomic mass.

How many ml of a 2.903 M NaOH solution are needed to produce 500.0 ml of a 0.3344M solution?
levacccp [35]

Answer:

57.6ml

Explanation:

Using dilution formula

C1V1 = C2V2

C1 = 2.903 M, V1 = ? , C2 = 0.3344 M , V2 = 500ml

2.903 × V1 = 0.3344 × 500

V1 =( 0.3344 × 500)/ 2.903

= 57.5956

≈ 57.6ml
