Q1. Which root word corresponds to four carbon atoms?
- A.pent
- B.prop
- C.but
- D.eth
Answer: C. but
Q2. Which is correctly named?
- A.CH4 is methanol
- B.CH3COOH is ethanol
- C.C2H5OH is ethanol
- D.C2H4 is ethane
Answer: C. C2H5OH is ethanol
Asked for the unknown; data is laid out in the stem. By F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2). F = m*a, V = I*R, n = m/M, v = f*lambda, KE = (1/2) m v^2) → hence the required answer = C2H5OH is ethanol. recall the defining law / equation for the named quantity (e.g. Hence option C) C2H5OH is ethanol. Others fail: option A) 'CH4 is methanol' is wrong because CH4 is methane; option B) 'CH3COOH is ethanol' doesn't hold - CH3COOH is ethanoic acid.
Q3. A saturated open-chain hydrocarbon is built from 1 carbon atoms linked only by single bonds; what is its IUPAC name?
- A.methane
- B.propane
- C.ethane
- D.methene
Answer: A. methane
With 1 carbons and only single bonds it is an alkane (CnH2n+2). The stem for 1 carbons is 'meth' and the suffix is '-ane', giving methane.
