The following are the ways in which farmers depend on communication technology and modern communication systems:
Farmers rely on mediums like radio, television, and the internet in order to get information pertaining to weather and other factors that affect the crop directly and indirectly. Based on the weather forecast reports presented on radio and television, the farmers plan their activities in order to minimize the possibilities of loss if there are predictions of less or no rainfall in the coming days.
Moreover, the farmers make use of the communication technology to contact the buyers or vendors from not only the domestic markets, but also those from the international market.
Modern communication systems help the farmers by bringing them across the information pertaining to new and improved varieties of seeds, fertilizers, agricultural equipment, etc., and make them aware of convenient yet efficient means of carrying out agricultural activities.
SN2 reaction proceeds with inversion of configuration at the reacting carbon atom. The product has a different configuration at this carbon atom from the product.
SN2 reaction is a short form for substitution nucleophilic bimolecular reaction. It is a synchronous reaction in which the leaving group departs at the same time as the nucleophile attacks in a single transition state.
Recall that SN2 reaction proceeds with inversion of configuration hence the product has a different configuration at the reacting carbon atom from the product. The inorganic product in this reaction is HI. The organic product is shown in the image attached to this answer.
