Clear indication of dyslexia requiring immediate intervention
Normal developmental stage involving hemispheric integration✔️
Evidence of visual processing disorder
Sign of inadequate prior instruction

Chemistry QUESTION #7194

Question 3432

Which of the following organic compounds will not produce a precipitate when heated with $AgNO_{3}$ after Lassaigne's test fusion with metallic sodium?

$C_{6}H_{5}NH_{2}$✔️
$C_{6}H_{5}Cl$
$CH_{3}Cl$
$CH_{2}Cl_{2}$

Correct Answer Logic:

Lassaigne's test is used to detect Nitrogen, Halogens, and Sulfur. However, the compound must contain Carbon and Nitrogen (to form $CN^-$) or a Halogen (to form $X^-$) to give a positive result with $AgNO_3$.

Aniline ($C_{6}H_{5}NH_{2}$) contains nitrogen, which forms $NaCN$. When reacted with $AgNO_3$, it doesn't give a halide precipitate like the other options which contain chlorine [cite: 3, 4].
$C_{6}H_{5}Cl$, $CH_{3}Cl$, and $CH_{2}Cl_{2}$ all contain Chlorine and will form a white precipitate of $AgCl$[cite: 25, 26].

Chemistry QUESTION #7395

Question 3433

The most basic oxide among the following is:

SeO₂
Al₂O₃
Sb₂O₃
Bi₂O₃✔️

Correct Answer Logic:

Metallic character and basicity of oxides:
Basic character of oxides increases with metallic character. In group 15: N₂O₃ (acidic) → P₄O₆ (acidic) → As₂O₃ (weakly acidic/amphoteric) → Sb₂O₃ (amphoteric) → Bi₂O₃ (basic).

Bi is the most metallic of the group 15 elements. SeO₂ and Al₂O₃ are amphoteric. Bi₂O₃ is the most basic oxide listed.
