Do we have less face-to-face interaction because of social networks - Research Paper Example These have made it easy for people to communicate with anyone irrespective of their geographical location. Social networks have brought innovative ideas. Currently, social games have taken away the free time that people used to have and share with friends. People especially the young generation are spending much of their time playing games and chatting with friends. Although a certain school of thought argues that this reduces boredom, the role that family members and friends played cannot be replaced by social network. Statistics indicates that the number of stress-related diseases has increased tremendously especially among the young people. This is because they no longer share their feeling which cannot only be done through face-to-face interactions. On the other hand, the number of people suffering from obesity and other diseases related to less physical activities has increased. This is because people no longer walk or jog. Instead, they spend much of the time interacting throug h the social network. A quantitative method was used in order to collect information concerning the topic of study. This was crucial in coming up with an in-depth conclusion on whether the social network has played a significant role in reducing face-face interactions. A sampling method was used to determine the number of people who use social networks to chat with friends and family members. The samples were selected randomly in order to avoid any cases of biasness. This was significant in ensuring that the information obtained was reliable and up-to-date Qualitative research was also conducted. The nature of the problem could not be understood through exploratory research only. The use of sampling ensured a reduced survey bias through the use of focus groups. It also ensured that the ideas from a broad spectrum have been used before making the final findings and conclusion. The wide amount of views was important in ensuring that questionnaire constructed was

Organic chemistry - Essay Example A careful look at the peaks results displayed by the NMR of the substance is also required. A singlet peak at a chemical shift value of 11.1ppm confirms the presence of the COOH group. Peak at 2.4ppm is due to the presence of the group R-C=O attached to CH. Applying the n+1 rule we know that the methylene or the CH2 group will be able to interact with the three hydrogen of the methyl or the CH3 group, hence (3+1)=4 peaks or a quadruplet is obtained. Similarly the three hydrogen atoms of methyl are ale to interact with the 2 hydrogen of methylene, hence (2+1) =3 or a triplet peak is displayed. The ratio obtained is determined by the relative heights of the respective peaks. Peak at 3330 per cm at the infra red spectrum is due to the high absorption range of the O-H group in the compound, whereas peaks centered at 2900 per cm is due to the presence of C-H bonds in the compound. M-1 peak of 60 is the RMM of the compound (12*3) + (1*8) + 16= 60 atomic mass unit, peak at 31 confirms the presence of CH2OH: 12+2+16+1=31, C2H3 gives peak at 27: (12*2) + (1*3), C3H7O :( 12*3) + (1*7) + 16=59. 3.6ppm value at the NMR suggests the presence of R-OH functional group. The single hydrogen is able to interact with the neighboring hydrogen of the CH2 group hence a triplet is obtained. A singlet peak at a chemical shift of 2.2ppm shows the presence of the R-C-O fragment. 6 peaks at 1.6ppm are obtained due to the presence of R3CH where single hydrogen is able to interact with 5 neighboring hydrogen giving 6 peaks. Triplet of 0.9ppm is present due to R-CH3 as three hydrogen interact with the neighboring 2 of the CH2 giving a triplet peak (2+1). The ratio of 2:1:2:3 provides us the different environments of the protons. Percentages of carbon, hydrogen and an unknown element are 45.9%, 8.9% and 45.2% respectively. Dividing them by their respective relative molecular masses 45.9/12, 8.9/1 and 45.2/35.5, it is found out that the other element is chlorine as the percentage
