Answer:
not aromatic
Explanation:
Cyclopropene -
as the compound is is made to lose a proton , and gains a negative charge on its ring ,
Now, The ring can become aromatic or anti - aromatic depending on the number of π electrobns ,
According to Huckel 's rule ,
The cyclic compounds with ( 4n+2 ) π electrons , where , n = 0, 1, 2, 3 ... , are considered to be aromatic in nature ,
And the cyclic compounds with ( 4n ) π electrons , where , n = 1, 2, 3 ... , are considered to be anti - aromatic in nature.
Now, for the cyclopropene structure , the number of π electron are equal to 4 , 2 from the double bond and 2 from the negative charge .
Therefore , the compound becomes not aromatic or anti - aromatic .
Answer : The mass of produced will be, 49.32 Kg
Explanation : Given,
Mass of = 26.1 Kg = 26100 g
Molar mass of = 26.98 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react to give 1 mole of
So, 967.38 moles of react to give
moles of
Now we have to calculate the mass of .
Therefore, the mass of produced will be, 49.32 Kg
