Refer to the given number, symbol series and answer the question that follows. Counting to be done from left to right only.
(Left) 6 # 1 * 8 & 7 & 5 4 Ω 3 % 9 6 @ 2 $ 9 £ 3 (Right)
How many such symbols are there each of which is immediately preceded by an odd number but NOT immediately followed by an even number?
AFour
BTwo
COne
DThree
Show answerHide answer
Correct answer: (C) One
Explanation
Official answer key: (3) One
Correct answer should be (4) Three. Symbols immediately preceded by an odd number are * (1 * 8), & (7 & 5), % (3 % 9) and £ (9 £ 3). Only * is followed by an even number, so three symbols (&, %, £) satisfy the condition.
Scoring follows the official key.

Which of the following is NOT a homologous series?
AC₂H₄ , C₂H₆ , C₃H₆ , C₄H₈

CCH₄ , C₂H₆ , C₃H₈ , C₄H₁₀
DC₃H₇OH , C₄H₉OH , C₅H₁₁OH_, C₆H₁₁OH
Show answerHide answer
Correct answer: (A) C₂H₄ , C₂H₆ , C₃H₆ , C₄H₈
Explanation
Official answer key: (1) C₂H₄ , C₂H₆ , C₃H₆ , C₄H₈
This question is flawed: option 2 (C₂H₂ is an alkyne, the rest are alkenes) and option 4 (C₆H₁₁OH should be C₆H₁₃OH) are also not homologous series. Option 1 is clearly not one: C₂H₄, C₃H₆, C₄H₈ are alkenes but C₂H₆ is an alkane, and C₂H₆ does not differ from C₂H₄ by CH₂.
Scoring follows the official key.
