User: You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.

Title: Fractional Distillation - Detailed Explanation Along With Diagrams - BYJU&#x27;S
Content: <b>Fractional</b> <b>distillation</b> <b>is</b> a type of <b>distillation</b> which involves the separation of miscible liquids. The process involves repeated <b>distillations</b> and condensations and the mixture is <b>usually</b> separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

Title: Fractional Distillation of Ideal Mixtures - Chemistry LibreTexts
Content: Relating what happens in the fractionating column to the phase diagram. Suppose you boil a mixture with composition C 1. The vapor over the top of the boiling liquid will be richer in the more volatile component, and will have the composition C 2. That vapor now starts to travel up the fractionating column.

Title: 5.3A: Theory of Fractional Distillation - Chemistry LibreTexts
Content: A simple <b>distillation</b> <b>is</b> incapable of significant purification if the boiling points of the components are too close. When the difference in boiling points is less than \(100^\text{o} \text{C}\), a modification is necessary, namely insertion of a fractionating column between the distilling flask and three-way adapter (Figure 5.37a).
