Most DAT students get this wrong — and it costs easy points on test day. The pattern is simple once you see it: Excess CH₃I → forms a quaternary ammonium salt Ag₂O / H₂O → converts it to a hydroxide Heat → Hofmann elimination (least substituted alkene wins) The key idea: Hofmann...

Fractions and proportions are a core part of the DAT Math (Quantitative Reasoning) section and appear frequently in multi-step word problems. In this video, Professor Blois walks through how to approach fraction-based problems step by step. Students often ask which DAT study materials are...

Here is a classic DAT-style math question where students often lose track of the fractions across multiple steps. The key is recognizing where the 8 students come from — they represent the group that took chemistry but did not take biology. Following the fractions step by step leads directly...
