Answer : The correct option is, (A) 7-chloro-3-ethyl-4-methyl-3-heptene
Explanation :
The rules for naming of alkene are :
First select the longest possible carbon chain.
The longest possible carbon chain should include the carbons of double bonds.
The naming of alkene by adding the suffix -ene.
The numbering is done in such a way that first carbon of double bond gets the lowest number.
The carbon atoms of the double bond get the preference over the other substituents present in the parent chain.
If two or more similar alkyl groups are present in a compound, the words di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.
The given compound name will be, 7-chloro-3-ethyl-4-methyl-3-heptene.
The structure of given compound is shown below.
Answer:
C) 75.78 g
Explanation:
Given parameters:
Volume of cloud = 94.2L
Molar mass of water = 18.02g/mol
Unknown:
Mass of water = ?
Solution:
Water is the bulk component of a cloud. To solve this problem, let us find the number of moles of the water using the relationship below first;
Number of moles of water =
Number of moles of water = = 4.21moles
Now to find the number of moles;
Mass of water = number of moles of water x molar mass
= 4.21 moles x 18.02g/mole
= 75.78 g
