(5) The correct option is, pentanoic acid
Explanation :
The basic rules for the naming of organic compounds are :
- First select the longest possible carbon chain.
- The longest possible carbon chain should include the carbons of double or triple bonds.
- The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne and carboxylic acid by adding the suffix -oic acid.
- The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.
- The carbon atoms of the double or triple 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.
It tell the number of electrons
put 8 in front of the oxygen in the reactants side to make it 16 molecules then put a 5 in front of the co2 in the product side to balance the carbon atoms then put a 6 in front of the H20 on the product side this balances both the hydrogen and oxygen atoms here is a representation
C5H12(g)+8O2(g)=5CO2(g)+6H20
The correct answer is letter B. Genetic engineering has shown a great leap in Science because we can now harness the ability of mutations of cells in crops and in other aspects. Flour is a commodity that is greatly needed by the masses and learning how to genetically modify its components to help it breed better is a great advantage for any society.
