Answer: The name of given molecule is
3-Methylpent-2-ene.
Explanation: First of all a carbon chain of five carbons was drawn. Then a double bond was made between carbon 3 and 4 (starting from left). A methyl group was drawn at middle carbon which is at position 3.
Molecule sketched was named as,
1) A longest chain containing double bond was selected and numbering was started from the end closest to double bond. Hence,
2-Pentene or
Pent-2-ene2) The position of substituent was specified before the parent name, Hence,
3-Methyl-2-Pentene or
3-Methylpent-2-ene
Answer:
Ionic bonds are more powerful than covalant bonds
Explanation:
This is because of their strong lattice structure formed by the attraction between metals and non-merals.
Molecules donot exhibit crystal lattices because of the covslent bonds present in between their molecules
