A) 14.3% less than original value
B) 14.3% greater than original value
C) 28.6% less than original value
D) 28.6% greater than original value
Correct Answer: A
Solution :
[a] Idea: To solve this problem complete the all reaction then choose the correct option. |
Number of protons in \[_{6}{{C}^{14}}=6\] |
Number of neutrons in\[_{6}{{C}^{14}}=8\] |
New atomic mass of \[_{6}{{C}^{14}}=\frac{8}{2}\times 6\times 2\] |
\[=4+16=16\] |
% increase in mass \[=\frac{16-14}{14}\times 100=14.3%\] |
TEST Edge: In JEE Main these type of questions are asked frequently, so students are advised to go through broad and clear understanding of preparation of various hydrocarbon and their derivatives such as alkenes, alkyl halide, aldehyde amines etc. |
