Answer: 2,5-dimethyl octane.
Explanation:
The basic rules for naming of organic compounds are :
1. First select the longest possible carbon chain.
2. The longest possible carbon chain should include the carbons of double or triple bonds.
3. 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.
4. The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.
5. The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.
6. 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.
Thus the name for straight chain made of 8 carbons with groups on the second and fifth carbons will be 2,5-dimethyl octane.
We know, by law of constant proportion :
Chemical compounds always contains its component in constant fixed ratio or in fixed percentage without depend on its source, method of preparation and mass of compound.
Therefore, percentage of oxygen is same for any mass.
Hence, this is the required solution.
The statement in option B is not correct. B is the correct answer. This is because nuclear fission usually occur in large unstable isotopes, which are bombarded with high speed particles like neutrons, which make them to split into smaller particles. The statement in option A, C and D are true about nuclear fission.
Answer. One of the key components of the softgel capsule is the plasticizer used to make the shell elastic and pliable and to minimize brittleness and cracking. The plasticizer usually accounts for 20-30% of the wet gel formulation which can impact the quality of the finished product.
