Write the IUPAC name of the product formed in the Reimer-Tiemann reaction.
The Reimer-Tiemann reaction is a method used for the ortho-formylation of phenols. It involves the introduction of a formyl group (-CHO) to the aromatic ring of phenol using chloroform (CHCl₃) in the presence of a strong base, typically sodium hydroxide (NaOH).
The general reaction can be represented as: \[ \text{C}_6\text{H}_5\text{OH} + \text{CHCl}_3 + \text{NaOH} \rightarrow \text{2-formylphenol} + \text{by-products} \]
The product of the Reimer-Tiemann reaction is 2-formylphenol, also known as ortho-hydroxybenzaldehyde.
The IUPAC name of the product formed in the Reimer-Tiemann reaction is 2-formylphenol.
In this reaction, the formyl group (-CHO) is added to the ortho position (adjacent to the hydroxyl group -OH) on the benzene ring.
Therefore, the IUPAC name of the product formed in the Reimer-Tiemann reaction is 2-formylphenol.
Arrange the following compounds in increasing order of their boiling points:

In the reaction R–OH + HCl $\xrightarrow{\text{ZnCl}_2}$ RCl + H$_2$O, what is the correct order of reactivity of alcohols?

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
