The given reaction sequence is Victor Mayer test to distinguish between primary secondary and tertiary alcohols. The primary alcohol reacts to give red colour of nitro alkane.
The secondary alcohol gives blue colour.
Tertiary alcohol does not react in the reaction.
Therefore the given alcohol is Tertiary alcohol.

In the following reaction sequence, R−OHP+I2→R−IAgNO2→R−NO2HNO2→no reaction. The alcohol is a:primary alcoholsecondary alcoholtertiary alcoholphenol

In the following reaction sequence, $R - O H P + I_{2} \to R - I A g N O_{2} \to R - N O_{2} H N O_{2} \to$ no reaction.
The alcohol is a:

primary alcohol
secondary alcohol
tertiary alcohol
phenol
