Finished In Front Of The Toilet

Exhausted from helping to prepare multiple answers to multiple papers (gosh this year’s exam timetables are really MEH 🙁 ), I once again slumped against my chair at The Temple in front of what is possibly the most beautiful, most ammonia (NH₃) pungent smell-free toilet you’ll ever find in any tuition centre in Singapore 😛

Twin Temple Toilets

The Temple‘s twin toilet – obsessively cleaned of *ahem* “organic compounds” to ensure a pleasant stay

It’s been raining all morning, but thankfully the gloomy weather didn’t translate into doom and gloom in today’s O Level Chemistry MCQ paper.

The list of workings and explanations for each of the answers (where applicable) for the GCE O Level 2013 Chemistry Paper 1 MCQ have been compiled!

Latest versions:

  • 1.2: Added further explanations to:
    Q16 – Why Y is not oxidation due to unchanged oxidation state of elements in ethanoic acid.
    Q32 – Why nitrogen does not undergo a reaction in the blast furnace.
    Q36 – Note on cis-trans isomers *sigh*
  • 1.1: Q23 – corrected typo in explanation. Should be options A, B & C excluded.
