Answer:
1,45 mL
Explanation:
The Grignard reaction is a very important organometallic chemical reaction where the Grignard reagent ( alkyl, vinyl, or aryl-magnesium halides) acts as nucleophile in order to the formation of Carbon-Carbon bonds.
In the problem, the phenylmagnesium chloride is the grignard reagent. The volume of 2.0 M phenylmagnesium chloride solution you need to add 2.9 mmol is:
2,9 mmol × = <em>1,45 mL</em>

Answer : The number of lone pairs of electrons around the central iodine atom are, 6 electrons
Explanation :
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.
In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.
The given molecule is,
As we know that iodine ans chlorine has '7' valence electrons.
Therefore, the total number of valence electrons in = 7 + 2(7) + 1 = 22
According to Lewis-dot structure, there are 4 number of bonding electrons and 18 number of non-bonding electrons.
Hence, the number of lone pairs of electrons around the central iodine atom are, 6 electrons
