Answer 1

Reagent stiochemetry used for the below chemical reaction,

Sr. No.	Reagent Name	Molecular   Weight	Mass (g)	mmoles	equivalents	Density (g/ml)	Volume (ml)
1	Tetraphenylcyclopentadienone	384.47	1.225	3.186	1	-	-
2	Anthranilic acid	137.14	0.581	4.240	1.33	-	-
3	Isoamyl nitrite	117.15	0.475	4.057	1.27	0.872	0.545
4	Dimethoxyethane	90.12	15.756	-	-	0.867	18.17
	Theoretical product
	1,2,3,4-tetraphenylnapthalene	432.55	1.378	3.186
	Melting point of tetraphenylnapthalene	It exhibits a double melting point (196-199 °C and 203-205 °C). due to two crystaline forms.
	Catalyst used for the above reaction	No catalyst is needed.
