2-methylprop-1-ene is an isomer of?
3-methyl but-1-ene
2-methyl but-1-ene
but-2-ene
pent-2-ene
Correct answer is C
somers of Butene: are But-1-ene, But-2-ene, 2-Methylpropene / 2-methylprop-1-ene
C\(_6\)H\(_6\)
C\(_4\)H\(_{10}\)
C\(_5\)H\(_{10}\)
C\(_4\)H\(_6\)
Correct answer is D
C\(_x\)H\(_y\) + (x + y/4)O\(_2\) \(\to\) x CO\(_2\) + y/2 H\(_2\)O
89.6 dm\(^3\) \(\to\) x moles CO\(_2\)
22.4 dm\(^3\) \(\to\) 1 mole CO\(_2\)
x = \(\frac{89.6}{22.4}\)
= 4 moles CO\(_2\)
54g of H\(_2\)O \(\to\) k moles H\(_2\)O
18g H\(_2\)O \(\to\) 1 mole H\(_2\)O
k = \(\frac{54}{18}\)
= 3 moles H\(_2\)O
From the equation above,
x = 4
k = y/2 = 3
y/2 = 3 \(\implies\) y = 6
\(\therefore\) The hydrocarbon C\(_x\)H\(_y\) = C\(_4\)H\(_6\)
The IUPAC name for CH\(_3\)CH\(_2\)COOCH\(_2\)CH\(_3\) is
methylpropanoate
ethylethanoate
ethylpropanoate
methylethanoate
Correct answer is C

\(1.2 \times 10^{22}\)
\(1.2 \times 10^{23}\)
\(2.4 \times 10^{22}\)
\(2.4 \times 10^{23}\)
Correct answer is A
\(1mole = 6.02 \times 10^{23} ions\)
\(0.02moldm^{-3} = 0.02 \times 6.02 \times 10^{23}\)
=\(0.1204 \times 10^{23} = 1.204 \times 10^{22}\)
\(\approxeq 1.2 \times 10^{22}\)
Which of the following organic compounds can undergo both addition and substitution reactions?
Pentane
Benzene
Propane
Hexane
Correct answer is B
An example of benzene addition reaction is the formation of cyclohexane by a mix of benzene vapour and hydrogen passed over nickel catalyst; while chlorobenzene is formed by substitution reaction.
