environment of the main alkanes‚ alkenes‚ alkynes and cyclic hydrocarbons. Procedure: 1. Complete the following table with similarities and differences in hydrocarbons. 2. From the table set examples of compounds in their condensed formula‚ naming them correctly. 3. Search for information about an alkane. Indicate where it comes from‚ its uses‚ effects in the environment and the way we can avoid negative impacts of this compound. Results: 1. HYDROCARBONS Alkanes Alkenes Alkynes Cyclic

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

Chemistry Unit 1 – Revision Questions Chemistry 1A 1) Define an element. How many are there in the Periodic Table? 2) Write a table with the charges and masses of protons‚ neutrons and electrons. 3) Define atomic number and mass number. 4) Draw electron (energy level) diagrams for Be‚ S‚ Al‚ Cl and K. Also‚ write down the number of protons and neutrons for each. Finally‚ write the symbols (with mass no. and atomic no.) 5) Why have all Group 7 elements (halogens) got similar chemical properties

Lab #24- Preparation 4-Methylcyclohexene Introduction: The goals in this lab were to have a reaction occur with 4-methylcyclohexanol and an acid catalyst to form our product of 4-methylcyclohexene via an E1 reaction. This reaction is accomplished by removing the –OH group on 4-methylcyclohexanol via dehydration and to have a double bond form via a loss of a hydrogen on a β-Carbon. Many techniques and skills were developed in this lab. Among them were dehydration‚ isolation‚ drying

only carbon and hydrogen atoms. • There are 3 types of aliphatic hydrocarbons: o Alkanes ▪ A hydrocarbon with only single bonds between carbon atoms. ▪ General formula is Cn H2n+2 ▪ All alkanes have the ending –“ane” ▪ Any alkyl branches in the carbon chain have the suffix –“yl” ▪ The name of a branched alkane must indicate the point of attachment of the branch. o Alkenes ▪ A hydrocarbon that contains at least one carbon – carbon double bond. ▪ General

the type of bonding that exists between the carbons. There are hydrocarbons that contain only carbon-to-carbon single bonds and they are called alkanes. There are also hydrocarbons that contain only carbon-to-carbon single bonds but it is different from alkanes because their carbon atoms are bonded together to form rings. They are called cyclohexanes. Alkanes and cycloalkanes are also known as saturated molecules – containing only carbon-to-carbon single bonds. When we say that a hydrocarbon is saturated

representing an aromatic ring (Webbook.nist). Table 2 also exemplifies a peak was present at 2943 and 2970 cm^(-1). Alkanes have a literature range ranging from 3000-2800 cm^(-1)‚ therefore‚ these two peaks are representing alkanes present in the molecule. The literature IR spectrum of N‚N-diethyl-m-toluamide has two peaks at approximately 2970 and 2950 cm^(-1)‚ representing alkanes (Webbook.nist).
